The "V9.04G" suffix indicates a specific revision, meaning minor component values or layout changes may exist, but the core topology remains stable across production batches.
AC Input (110-240V) → EMI Filter → Bridge Rectifier → Bulk Capacitor (400V) ↓ PWM Controller IC (e.g., UC3844 or equivalent) ↓ Main Switching MOSFET (on heatsink) ↓ Flyback Transformer (primary side) ↓ Secondary Windings → Diodes + Capacitors → Linear Regulators → DC Outputs ↓ Feedback Optocoupler (to regulate primary) chk-v9.04g circuit diagram
For a detailed visual walkthrough of the board's layout and common test points, technical resources like the NXP Application Note for induction cookers provide excellent generic architectural guidance that matches the CHK-V9 series. The "V9
