How to quickly check the fault of the IGBT module?

Due to the unbalanced output voltage of the frequency converter (VFD), the motor shakes and the speed is unstable. In general, it is difficult to determine which drive is at fault without experience. At this time, the 2hz of the VFD can be started, and the voltage values of p-u, p-v, p-w and u-n, v-n and w-n can be measured respectively with the DC voltage range of the multimeter. These six voltages will be different at this time, and the higher voltage will be different. The following is a simple measurement method for IGBT modules.

IGBT failure cause analysis

The IGBT power module is a power module composed of insulated gate bipolar transistors (IGBT). Since the IGBT module is a MOSFET structure, the gate of the IGBT is electrically isolated from the emitter through an oxide film, which has excellent device performance. Widely used in servo motors, frequency converters, frequency conversion appliances and other fields.
