: Converts 220V AC input into high-voltage DC (around +310V) via a bridge rectifier and a large filter capacitor. It also includes a step-down Switch Mode Power Supply (SMPS) that provides +18V for the cooling fan and IGBT driver, and +5V for the microcontroller.
: Consists of the work coil (inductor) and high-voltage resonant capacitors. This stage facilitates the electromagnetic induction required to heat compatible cookware. chk-v9.04g circuit diagram
The is a widely used control board found in many popular induction cookers , most notably within the Philips Viva Collection (such as the HD4931,
The circuit is generally divided into several key stages that manage power conversion and user interface: Induction Cooker Circuit Design | PDF | Mains
If you are repairing a board with the CHK-V9.04G marking, focus on these critical components commonly available through electronics suppliers like DigiKey Electronics : Component Category Common Parts/Labels IGBT (e.g., FGA25N120) Switches the coil current. Rectification Bridge Rectifier Converts AC to DC. Protection Fuse (10A-15A) Protects against over-current. Filtering 5μF or 0.3μF Capacitors Smooths DC bus and handles resonance. Control PWM IC / MCU Brain of the unit. Common Repair Scenarios
: Often caused by a blown fuse or a failure in the AC-DC converter module (check the VIPer series or similar PWM ICs). Protection Fuse (10A-15A) Protects against over-current
, and HD4902 models). Understanding the circuit diagram of this board is essential for troubleshooting common issues like power failure, heating inconsistencies, or specific error codes (E1–E4). Core Functional Blocks of the CHK-V9.04G
