Use a (Dim Bulb Tester) when first powering up after a repair to prevent blowing the IGBT again.

Converts the 230V AC into DC.

The monitors the user interface and temperature sensors (Thermistor). chkv904g circuit diagram full

enters through a fuse and an NTC thermistor (to prevent inrush current). The Bridge Rectifier feeds the DC bus capacitor.

If safe, the MCU sends a to the Drive Circuit (often using transistors like S8050/S8550). Use a (Dim Bulb Tester) when first powering

Provides 5V and 18V for the microcontroller and cooling fan. 2. Key Components in the Full Diagram
