Figure 2.
The system proposed for the IGBT power module eval kit is composed of one control board
STEVAL-IHM010V1, one power board STEVAL-IHM011V1, one motor and the power
supply.
The control board STEVAL-IHM010V1 is a Microcontroller (ST7MC) based board that
provides the driving signals related to the motor selected and the driving strategies.
Driving signals are constituted of 6 PWM signals in the range of 0-5 V (see
High side/low side pairs of one signal for each leg. In the system proposed three legs are
present (three-phase inverter).
The Power Board STEVAL-IHM011V1 is based on a power module (STG3P2M10N60B)
that converts the control signal in the power signals to drive the motor. The connection
between the control board and the power board is performed through a dedicated 32-pin
connector called "motor control connector" (see
The IGBT power module eval kit is able to drive the following kinds of motors:
●
AC induction motor, sensored
●
Brushless permanent magnet motor (trapezoidal driven), sensored or sensorless
●
Brushless permanent magnet motor (sinusoidal driven), sensored
The power board is supplied by a high voltage AC power supply 220 V (or 110 V) with the
capability to generate current up to 10 amps.
2 The power board can accept control signals in the range of 0-3.3 V if the jumpers are
properly configured.
