STMicroelectronics STEVAL-CTM004V1 User manual

Introduction
The STEVAL-CTM009V1 evaluation kit for motor control is designed to demonstrate the capabilities of ST Power MOSFETs
based on STripFET™ F7 technology. The 100V STripFET™ F7 devices (STH31*N10F7) are ideal for low voltage (up to 48 V),
high current applications such as forklifts, golf carts and power tool.
The STEVAL-CTM004V1 power board features an insulated metal substrate (IMS), NTCs for thermal protection and decoupling
gate resistors for each power MOSFET. The board mounts ST devices in the H²PAK-6 package.
The driver stage is an STEVAL-CTM006V1 board with L6491 high current capability gate drivers to drive the power MOSFETs
and integrated comparator for protections. The driver board includes the ST motor control connector, so you can interface the
STEVAL-CTM009V1 with any ST MCU control board suitable for motor control (not included in the kit).
The system also has an STEVAL-CTM005V1 bus link capacitor board and an STEVAL-CTM008V1 current sensing board.

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 STEVAL-CTM006V1 driver board
5.1.1 Power supply section
The power supply section provides all the voltages necessary for the circuitry. The required input voltage is 8 to
36 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 3 A step-down switching regulator)
• +5V and +3.3V for the control board (via an A6902 1 A switch step-down regulator)
5.1.2 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 STM32 microcontroller unit.
Table 1. Input voltage bus and input signal to STM32 ADC channel
Input Voltage ADC input
48V 2.0V
75V (max value) 3.1V
5.1.3 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 the STM32 FOC SDK software library.

6STEVAL-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 7. STEVAL-CTM005V1 bus link capacitor board
6.1 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).
