Utilizes N-Channel Power MOSFETs or electro-mechanical relays. Flyback diodes (e.g., 1N4007 or fast-recovery FR107) are placed in parallel across all inductive relay coils to dissipate reverse-voltage transients during turn-off cycles. 3. Key Components and Reference Designators

CHK-V9.04G is a common control board typically used in high-power induction cookers

Trace the high-value voltage sensing resistors (240kΩ–470kΩ). If any of these resistors drift high in value or fail open-circuit, the MCU assumes there is an unsafe voltage fluctuation and halts operation.

The is a specific control board (PCB) commonly found in induction cookers , particularly those manufactured by Philips . Based on its design for high-power heating appliances, its primary features focus on power management, safety, and user interface control. Key Features of the CHK-V9.04G Circuit:

: Test the output rectifying diodes around the SMPS transformer area to ensure none are shorted.

Desolder the IGBT () and use a multimeter in diode mode to test for continuity between the Collector, Emitter, and Gate pins. A reading close to 0Ω indicates a catastrophically shorted IGBT.

: This typically means the pan is not detected. Ensure you are using ferromagnetic cookware (cast iron or magnetic stainless steel).

If you are upgrading or repairing a system utilizing the CHK-V9.04G schematic, observe the following electrical engineering guidelines:

Powers the cooling fan and provides the high-current turn-on voltage required by the IGBT gate driver circuit.

The CHK-V9.04G operates as an integrated power management and signal processing hub. The circuit architecture is designed to accept raw input power, stabilize it, process sensory inputs via a central microcontroller unit (MCU), and execute high-current output commands through solid-state switching components.

Check the primary side of the diagram. Is the fuse blown? Is the bridge rectifier outputting DC voltage?

Always use an isolated power supply or series lamp limiters when testing live.
