STEVAL-IHM035V2: 100W, 3-Phase BLDC Driver Board for FOC and Scalar Motor Control

The STEVAL-IHM035V2 3-phase high voltage inverter power board features the STGIPN3H60 (SLLIMM™-nano) for both field-oriented control (FOC) of permanent magnet synchronous motors (PMSM) and trapezoidal scalar control of brushless DC (BLDC) motors, this 3-phase inverter is designed to perform both the FOC of sinusoidal-shaped back-EMF PMSMs and trapezoidal control of BLDC motors with or without sensors, with nominal power up to 100 W. The flexible, open, high-performance design consists of a 3-phase inverter bridge based on:

• The STGIPN3H60 SLLIMM™-nano (small low-loss intelligent molded module) IPM, 3 A -600 V 3-phase IGBT inverter bridge

• The VIPer16 fixed frequency VIPer™ plus family

The system is specifically designed to achieve fast and accurate conditioning of the current feedback, thereby matching the requirements typical of high-end applications such as field oriented motor control. The board is compatible with 110 and 230 Vac mains, and includes a power supply stage with the VIPer16 to generate the +15 V and the +3.3 V (or optionally the +5 V) supply voltage required by the application. Finally, the board can be interfaced with the STM3210xx-EVAL (STM32 microcontroller evaluation board), through a dedicated connector.
