Description
The EVSPIN32F0251S1 board is a 3-phase complete inverter based on the STSPIN32F0251 controller, which embeds a 3-phase 250 V gate driver and a Cortex®-M0 STM32 MCU. The power stage features STD17NF25 MOSFETs, but can be populated with any IGBT or Power MOSFET in DPAK or powerFLAT 6x5 package.
The board has a single-shunt sensing topology, and both the field-oriented control FOC) and sensored or sensorless 6-step control can be implemented. This allows driving permanent magnet synchronous motors (PMSMs) and brushless DC (BLDC) motors.
The evaluation board is compatible with a wide range input voltage from 20 V to 120 V DC/AC, and includes a power supply stage with the VIPER013BLS in buck configuration to generate +15 V and +3.3 V supply voltage required by the application.
Debug and configuration of FW can be performed with standard STM32 tools through the detachable STLINK-debugger. SWD and UART TX-RX connectors are also available.
