Design of IGBT gate drive circuit based on ACPL-332J

The main circuit and related principles of inverter are briefly described in this paper, and then the IGBT driver and its fault protection circuit are designed in detail based on ACPL-332J chip. It is connected with 5SNA0800J450300 IGBT of ABB and applied in 3 300 V mine frequency converter. The results show that the drive circuit has high reliability and adaptability, and can be widely used in medium voltage and high power transmission.
