: 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.
: 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. 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. : Uses the PWM signal to switch an
The circuit is generally divided into several key stages that manage power conversion and user interface: chk-v9.04g circuit diagram
