High-power IGBT inverter module for MGE online UPS. It receives DC bus voltage and converts it into stable sine-wave AC output via high-frequency PWM modulation. Absorption capacitors and power resistors suppress switching spike. It cooperates with UPS control board to realize uninterrupted power switching, voltage regulation and fault protection.

Certification: CE, UL

IGBT power chips, high voltage absorption capacitor, power discharge resistor, copper busbar, drive circuit and power terminal. Common faults: IGBT breakdown, capacitor bulge, drive circuit failure, overcurrent shutdown and bus short circuit.
