5 kW low voltage high current inverter for industrial motor control applications
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.

STEVAL-CTM004V1 power board STEVAL-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. -
