4STEVAL-CTM004V1 power board
The STEVAL-CTM004V1 power board of the evaluation kit has 36 STH31*N10F7 N-channel Power MOSFETS in
the H²PAK-6 package. A gate resistor is placed near each power MOSFET to eliminate parasitic oscillation. A
pull-down resistor between the gate and the source of each transistor helps to avoid capacitive coupling driving
the transistor and unwanted switch-on when gate is floating. A snubber RC circuit on each switch limits the rate of
voltage 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 stress
on the devices. The capacitors reduce voltage overshoot caused by abrupt current change in the parasitic
inductors in the circuit.
To monitor the temperature of the power board and provide over-temperature protection, three NTCs are placed
on 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 the
bulk capacitor board connection and three towers near the motor connection.

5.1 Power supply section
The power supply section provides all the voltages necessary for the circuitry. The required input voltage is 8 to
25 V input, which is supplied through connector JP1.
The input voltage is then converted to the following voltage levels:
• +12V for gate driver section (via an A7986 which is a 3 A step-down switching regulator)
• +5V and +3.3V for the control board (via an A6902 which is a 1 A switch step-down regulator)
5.2 Bus voltage monitoring
Bus voltage monitoring is implemented across an input voltage range of 5 to 75 V.
The following table shows the measured input voltage and the corresponding voltage level sent to the ADC input
of the SPC5 microcontroller unit.
Table 1. Input voltage bus and input signal to SPC5 ADC channel
Input Voltage ADC input
48V 2.0V
75V (max value) 3.1V
5.3 Temperature monitor
Three NTCs are placed on the power section to provide temperature information, although only one NTC may be
chosen at a time. Close one of the three jumpers S1, S2 or S3 to read the temperature near the U, V or W phase,
respectively. The microcontroller monitors processed signals to determine the temperature of the driver board and
manage any overload or over-temperature conditions.
To protect the hardware from excess temperature, a safe threshold is set in SPC5-MCTK-LIB.

5.5 L9907 supply voltage configuration for 48 V applications
The L9907 automotive 3 phase BLDC driver has a default typical overvoltage threshold of 36 V. if 48 V is applied
to the VB pin, an OV error is triggered in the start phase with (B11) = ‘1’ in the DIAG register and the FS_FLAG
pin set to low.
As the VB pin is supplied from 48 V, the overvoltage protection VBov (B9) has to be disabled setting ‘0’ in CMD1
register. The overvoltage protection set on the boost regulator BST_C pin also needs to be disabled (default is set
to '0') by setting bit DIS_BSTov (B12) in CMD3 register to ’1’.
Note: This bit is only acknowledged if AND (EN1, EN2) = '0'. Trying to write it without lowering AND (EN1, EN2) will not
generate an SPI error, but the command will be ignored for the specific bit.
While setting CMD3 B12 to 1 disables the overvoltage protection on the BST_C pin, this solution does not allow
use of the FS_FLAG pin (which would always be low) to trigger an error in the microcontroller. This is due to the
fact that only the fault effect is disabled when VBov (B9) is set to ‘0’, while the fault is still latched in the SPI
register DIAG. Continuous polling must therefore be performed to query the device to verify whether errors are
present.

6Bus link capacitor board and current sensing board
6.1 STEVAL-CTM005V1 bus link capacitor board
In EV inverter systems, bus link capacitors reduce ripple current and suppress voltage spikes caused by leakage
inductance and switching operations. These capacitors provide a low impedance path for the ripple currents
caused 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 × Vbus
f×L
Where:
• 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 and
L = 12 μH). If we add 10% to ΔI0.5t and choose electrolytic capacitors with a ripple current of 2.4 A, 22 electrolytic
capacitors are required. The resulting capacitance is about 6 mF, leading to a negligible ripple voltage on the bus.
Figure 6. STEVAL-CTM005V1 bus link capacitor board
6.2 STEVAL-CTM008V1 current sensing board
The STEVAL-CTM008V1 current sensing board is a general purpose board for motor control that can read up to
three phase motor currents and DC bus currents if four ICS are on-board. The board included in the kit hosts two
ICS to read two phase currents.
This sensing feature determines motor currents for digital control based on FOC algorithms. The sensors provide
high 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 voltage
can be overdriven by providing an external reference voltage through the J1 connector. A female to female flat
cable 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).
