4 STEVAL-CTM004V1 power board

The STEVAL-CTM004V1 power board of the evaluation kit has 36 STH31*N10F7 N-channel Power MOSFETS inthe H²PAK-6 package. A gate resistor is placed near each power MOSFET to eliminate parasitic oscillation. Apull-down resistor between the gate and the source of each transistor helps to avoid capacitive coupling drivingthe transistor and unwanted switch-on when gate is floating. A snubber RC circuit on each switch limits the rate ofvoltage change during switching transitions to reduce electromagnetic interference (EMI) and losses.two decoupling capacitors close to the switching power MOSFETs reduce ringing on the VDS and voltage stresson the devices. The capacitors reduce voltage overshoot caused by abrupt current change in the parasiticinductors in the circuit.To monitor the temperature of the power board and provide over-temperature protection, three NTCs are placedon the power board near the drain of one power MOSFET for each inverter leg.The power section also has connectors for the driver board, with CON5 (phase_U), CON6 (phase_V) and CON7(phase_W) for gate driving and NTC sensing, and J3 for bus voltage. The board also hosts six towers near thebulk capacitor board connection and three towers near the motor connection.

6 STEVAL-CTM005V1 bus link capacitor board

In EV inverter systems, bus link capacitors reduce ripple current and suppress voltage spikes caused by leakageinductance and switching operations. These capacitors provide a low impedance path for the ripple currentscaused by output inductance load, the bus voltage and PWM frequency.The bus link capacitors must sustain a ripple current given by the following formula:ΔI0.5t = 0.25 × Vbusf × LWhere:• ΔI0.5t is the maximum ripple current when duty cycle is 50%• Vbus is the bus voltage• f is the switching frequency• L is the load inductance.

For a very low inductance motor (worst case scenario), ΔI0.5t is about 48 ARMS (Vbus = 52 V, f = 8 kHz andL = 12 μH). If we add 10% to ΔI0.5t and choose electrolytic capacitors with a ripple current of 2.4 A, 22 electrolyticcapacitors are required. The resulting capacitance is about 6 mF, leading to a negligible ripple voltage on the bus.

Figure 7. STEVAL-CTM005V1 bus link capacitor board

6.1 STEVAL-CTM008V1 current sensing boardThe STEVAL-CTM008V1 current sensing board is a general purpose board for motor control that can read up tothree phase motor currents and DC bus currents if four ICS are on-board. The board included in the kit hosts twoICS to read two phase currents.This sensing feature determines motor currents for digital control based on FOC algorithms. The sensors providehigh accuracy, with 4 mV/A over a temperature range of -40 °C to +105 °C and a nominal current of 200 ARMS.The internal reference voltage of the ICSs (according to their VCC) is generally used, but the reference voltagecan be overdriven by providing an external reference voltage through the J1 connector. A female to female flatcable is used to connect CON2 on the driver board with J1 on the current sensing board.The signals from the sensors center around 1.65 V (average value at zero current).
