Introduction

The STDES-7KWOBC is an on-board charger (OBC) reference design that allows charging the battery of electric vehicles (EV)through your home AC mains plug or a private/public outlet (AC charging station).The reference design embeds two sections: an interleaved totem pole PFC with SiC and a dual galvanic isolated full bridge LLCDC-DC ZVS resonant converter, based on MDmesh DM6 super-junction power MOSFETs.The power platform is a 7 kW module able to deliver a constant current (CC) or constant voltage (CV) on the output to be usedas standalone (1 PH+ N), in parallel or in 3-phase mode (3Ph + N) to reach 21 kW.The underlying insulated metal substrate (IMS) on aluminum base plate enables very effective heat dissipation, forced air orliquid cooling.Each module composing the reference design allows an easy interconnection among modules of the same type through wiresor bus bar connection, reaching a higher output power.This reference design key factor is the efficiency and high-power density gained thanks to SiC and SJ power MOSFETs,silicon and SiC diodes, gate drivers, the SPC58NN84E7RMHBR power architecture automotive-grade microcontroller, and SCRthyristors for inrush current limitation.The STDES-7KWOBC is a fully assembled kit developed for performance evaluation only, not available for sale.

2.2 ArchitectureThe STDES-7KWOBC consists of an AC-DC totem pole PFC and a DC-DC LLC resonant converter.

Figure 2. STDES-7KWOBC topology

The switching frequency of the interleaved totem pole PFC is 70 kHz, whereas for the dual DC-DC LLC resonantconverter is in the range of 80 to 310 kHz.The interleaved totem pole features an inductor current balanced control while the DC-DC LLC features outputcurrent balance control. These functions ensure a balanced current of the parallel connection stages.The AC-DC totem pole PFC section converts an input voltage of 85 VAC to 265 VAC into 400 V. The maximuminput current is 32 A at 50 Hz or 60 Hz.The PFC works in continuous conduction mode (CCM). The TN3050H-12GY-TR SCR thyristors implement inrushcurrent with a dynamic resistance of 14 mohm. PID or 2p2 controllers regulate the current via two independentcurrent loop regulators. These controls are implemented on the SPC58NN84E7RMHBR MCU controller.The second converter is the dual resonant DC-DC LLC based on super junction MOSFETs.The output DC-DC voltage is in the range of 250 VDC to 450 VDC. Two independent constant current loops (CC)and one constant voltage loop (CV) plus current balancing are implemented on a second SPC58NN84E7RMHBRMCU controller.

4 Control board and cable connections

The STDES-7KWOBC platform can manage up to 7 kW of power across the operating input voltage range. Forfunctional and efficiency testing, use the following equipment:• a 7500 W programmable AC voltage source• 500 V max / 28 A DC electronic load• a power analyzer (optional)• a digital oscilloscope (optional)

Step 1. Connect the programmed control board to the 64-pin connector.PFC section and LLC section work with different firmware.The control boards of the platform are already programmed and ready to use, thus you do not need toload firmware.To program a new control board, power it with an external 5 V supply through J3 connector of thecontrol board.

Note: Do not connect the control board to the power board for this operation.

Note: Do not swap the control boards.

Step 2. Connect the programmable AC voltage source to the board AC input voltage, respecting the cross-section gauge to sustain 32 A.

Step 3. Connect the output load to J28-J29 connectors with a cable of appropriate cross-section to carry thedesired load current (28 A max.).

Note: Always connect the earth to the input connector.

Step 4. Ensure the STDES-7KWOBC is not powered.

5 Architecture and implementation

The PFC section is an interleaved totem pole that uses 2 x 510 µH inductors and 2240 µF bulk capacitors. Theswitching frequency is 70 kHz. The HF legs use SiC MOSFETs (STB47N60DM6AG) and the low frequency leg isSCR-based (TN3050H-12GY-TR).This PFC is designed to work in continuous conduction mode (CCM) using average current control with twoindependent current loops (type II or PID), mains voltage feedforward, PWM startup at zero crossing to avoidcurrent spikes.

Figure 9. Average current control - block diagram

5.1 Voltage feedforwardThe RMS mains voltage value (Vrms) allows calculating the input current reference:iref = Vreg_out ⋅ VmainsVrms2 (1)

Being the Vrms value proportional to mains average value, the last one is calculated using a digital low passfilter with 10.6 Hz cut-off frequency and 0.011 gain, in order to limit third harmonic content at 0.75%, on currentreference. The figure below shows the result of the digital filter on a 6 kHz sampled test signal (red stars)comparing the result given by MATLAB (blue squares) and what computed by the MCU (black dots).

Figure 10. Absolute sampled value of Vmains

Figure 11. Filter output comparison

Note: • 1Vrms2 assures constant power if input voltage changes;

• a low pass digital filter calculates Vrms to limit the second harmonic distortion, and then third harmoniccontent of line current, in order to meet EN-61000-3-2 standard;

• digital filter parameters: mains voltage sampled at 6 kHz, third harmonic = 0.75%, gain = 0.011, cut-offfrequency = 10.61 Hz;

• the filter is designed through MATLAB; the output of the MATLAB filter and the MCU results using testsignal (Vtest = 2 ⋅ 230 ⋅ sin 2π ⋅ 50 ⋅ t ) are the same.

UM2940 - Rev 2 page 12/76

5.2 Type II digital controller• Mostly used for current controllers (two poles and one zero):

H s = ωp0s × sωz1 + 1sωp2 + 1• Applying bilinear transformation (s = 2T ⋅ 1− z−11 + z−1 ), we obtain a two-pole, two zero digital controller:

H z = y zx z = B2z−2 + B1z−1 + B0−A2z−2 + A1z−1 + 1• Linear differential equation (LDE):y n = A1y n − 1 + A2y n − 2 + B0x n + B1x n − 1 + B2x n − 2

5.3 PFC current controller• Independent controllers for each HF leg executed cycle by cycle at PWM frequency (70 kHz);• Selectable PID or two-pole, two-zero controller;• Designed in frequency domain to satisfy the stability criteria of phase margin and crossover frequency

(φm ≥ 45°), with Fx between 2 and 10 kHz;• LDE coefficient calculation executed in MATLAB and pasted in C code;• Same results using exact or simplified plant model (at high frequency the exact model plot converges to the

5.5 Inrush current limiterAt startup, when DC bus capacitors are discharged, the mains might absorb a high current. Usually, an NTCresistor and a bypass relay can limit the inrush current.Using SCRs in PFC low frequency leg and adopting a progressive phase control at board startup, you can limitinrush current without the need of NTC and relay.At steady state, SCRs are driven with 50% duty cycle, and with a safe dead time, synchronized with the mains.With the totem pole PFC using the SCRs, the bus capacitor can be smoothly charged with a progressive phasecontrol, avoiding the use of an NTC or a resistor.

UM2940Inrush current limiter

UM2940 - Rev 2 page 15/76

Figure 15. Interleaved PFC totem pole topology with SCRs

As long as the SCRs are not driven, the bridge does not conduct the current and the DC bus capacitors are notcharged. To start charging the DC capacitors, SCR T1 and SCR T2 have to be turned on according to the ACline voltage polarity (T1 is turned on when the AC line polarity is negative and T2 is turned on when the AC linepolarity is positive).To reduce the inrush current, the SCRs are alternatively triggered at the end of the half line voltage cycle, just afew hundreds of microseconds before the line zero voltage. This allows the output capacitor to be charged to alow level (around 10 to 30 V) and not directly to the peak line voltage. The current driven from the line is thenmuch lower than in the case of a direct full charge of the DC capacitor.This soft start solution can work only when an inductor is present on the line side as the rate of the currentincrease has also to be limited to prevent SCR damage. The inductor is already present for most applicationswhere the EMI filter usually embeds a common mode choke, which has a differential mode parasitic inductor dueto the copper turns of the windings.To control the inrush current at PFC board startup with the SCRs, a solution has been implemented in the MCUfirmware: the variable SCRs on the delays allow a complete charge of this capacitor to the peak line voltage.SCRs have to be triggered on the subsequent half cycle with a shorter turn on delay than the one used to startcharging.

UM2940Inrush current limiter

UM2940 - Rev 2 page 16/76

Figure 16. SCRs driving signals and DC bus charging

By reducing the SCR turn-on delay by few tens or hundreds of microseconds from half-cycle to half-cycle, theoutput capacitor is progressively charged while the line current is kept low. The step of the SCR turn-on delayreduction is constant from one half-cycle to the following one.The SCR1 and SCR2 TON start at 30 µs and 60 µs, respectively. Each TON is incremented step-by-step by a ΔT(30 µs) until reaching a quarter of the mains period. When the mains voltage reaches its peak value, then the ONtime is equal to the half mains period, with a short time interval, before and after the mains zero crossing, in whichboth devices are not driven (Figure 16).

5.6 SCR control signalsA zero crossing detection (ZCD) signal, which gives the mains polarity and comes from a comparator, detectsboth the mains frequency and the duty (it should be around 50%) using a timer in input mode, and synchronizeslow frequency PWM signals (that is the synchronization of another timer).The figure below shows:• dc that represents the delay of the comparator output;• dr1 that is the delay rising of the SCR1 turn on with respect to the rising edge of ZCD in steady state (when

the inrush procedure is completed);• df1 is the falling delay of the same signal respect to the falling edge of ZCD with one programmable value• dr2 and df2 are rising and falling delays of SCR2 driving signal respect to ZCD.All these delays are defined and can be changed in the control firmware.

6 PFC control signals

Figure 18. Interleaved totem pole PFC signals

Current sampling is performed in the middle point of the TON PFC switching period.In the bridgeless totem pole PFC, the roles of the switches in the high frequency legs depend on the mainspolarity: when the mains voltage is positive, Q2 and Q4 (low side) are the active switches, whereas Q1 and Q3(high side) are driven in a complementary way with a fixed dead time. In the latter case, the current can circulate,in the low frequency leg, through T2, whereas T1 is off.During the negative mains voltage half cycle, Q1 and Q3 (high side) are the active switches, whereas Q2 andQ4 (low side) are driven in a complementary way with a fixed dead time. In the latter case, the current circulatesthrough T1 in the low frequency leg.To generate the necessary four PWMs signals, two different timers, with the phase shifted by 180°, are used toobtain an interleaving driving and to minimize the input current ripple.At the TON period midpoint of each active switch, an injected acquisition of the related inductor current is triggeredby the ADC. At the end of each conversion, once obtained the last current measure, the current control algorithmis executed and the new duty cycle value is written in the timer registers before the end of the actual periodbecomes effective at the next PWM cycle.

The DC-DC LLC section features:• Dual full bridge LLC with CC/CV control mode:• Two independent current loops (CC)• One voltage loop plus current balancing (CV)• Transformers:

7.1 FB LLC control signals

Figure 20. LLC main schematic and switching periods

The command signals for each LLC resonant full bridge converter are square waves with 50% duty and deadtime. Each PWM group mentioned as PWM7 and PWM8 in the figure above is used at the same time for Q7-Q10and Q9-Q8, respectively. The same is for PWM9 and PW10 for Q11-Q14 and Q13-Q12, respectively.In the constant voltage mode, the two full bridge LLC converters can be driven in the interleaved mode. In thiscase, the PWM signals have the same frequency and are 90 degrees shifted. However, due to the tolerance ofthe electric parameters of the two resonant tanks, the output current balance is not ensured.A dedicated control has been implemented to solve the unbalanced current issue. If a certain unbalance on theoutput current is present, the control provides a change on the PWM9 frequency with respect to the PWM7. AΔfs is introduced thanks to a PI regulator, executed at a lower frequency, to obtain the switching frequency of thesecond converter (fs2) in order to balance the output currents of the two stages (see the figure below).

In this case, the current loops are independent. The two switching frequencies, fs1 and fs2, are generated by twodifferent current regulators.The charger is able to switch from the constant current to the constant voltage mode via firmware, depending onthe battery voltage value and following the desired charging profile.
