Usually large 0.27µF to 0.33µF (1200V) capacitors that work with the induction coil.
Comprehensive Guide to the CHKV904G Circuit Diagram If you are working on repairing or hobbyist projects involving the (often associated with induction cooktop power boards or specific SMPS modules), having a clear understanding of its circuit diagram is essential. This board serves as the "brain" and "muscle" of the appliance, managing high-voltage switching and thermal safety.
Check the detection resistors (high wattage, high resistance). IGBT Drive Circuit Check the 18V rail and the drive transistors. Intermittent Off Overheating chkv904g circuit diagram full
Ensure the thermal paste on the IGBT and Bridge Rectifier is fresh and making good contact with the heatsink. Conclusion
Converts the 230V AC into DC.
Provides 5V and 18V for the microcontroller and cooling fan. 2. Key Components in the Full Diagram
Filters noise and protects against surges. Usually large 0
Use a (Dim Bulb Tester) when first powering up after a repair to prevent blowing the IGBT again.
