: Typically indicates a problem with the mains voltage being too low or too high. chk-v9.04g circuit diagram

: Consists of the work coil (inductor) and high-voltage resonant capacitors. This stage facilitates the electromagnetic induction required to heat compatible cookware. Induction Cooker Circuit Design | PDF | Mains

: Often a specialized 8-bit chip, such as an ST7FLITE09 or S3F84B8, that generates Pulse Width Modulation (PWM) signals to control the heating power. : Often a specialized 8-bit chip, such as

: 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.

: Uses the PWM signal to switch an Insulated Gate Bipolar Transistor (IGBT) . This high-power transistor switches current through the induction coil at high frequencies to generate the magnetic field.

The circuit is generally divided into several key stages that manage power conversion and user interface:
