DC Mosfet part of BP Series 600W inverter damaged during full load operation

DC Mosfet part of BP Series 600W inverter damaged during full load operation


Model

BP Series Pure Sine Wave Inverter 600W 220VAC


Description

The 600W inverter works normally when it is loaded with 600W or less, but the full load operation will quickly lead front MOSFET damaged.


Analysis of the possibility of the cause
1. After power-on test, the actual situation is that only two of the four front MOSFET are working, which will cause problems when fully loaded.
2. Inspection found that the fast recovery diode used for rectification of DP1 is damaged.


Solutions and steps

Replace the damaged diode.
