: Often caused by a blown fuse or a failure in the AC-DC converter module (check the VIPer series or similar PWM ICs). chk-v9.04g circuit diagram
: Often a specialized 8-bit chip, such as an ST7FLITE09 or S3F84B8, that generates Pulse Width Modulation (PWM) signals to control the heating power. Induction Cooker Circuit Design | PDF | Mains
: 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. It also includes a step-down Switch Mode Power
: Monitors temperatures via thermistors located under the glass surface and the IGBT heatsink. These sensors prevent overheating by providing feedback to the MCU. Troubleshooting and Component Identification
The circuit is generally divided into several key stages that manage power conversion and user interface:
The is a widely used control board found in many popular induction cookers , most notably within the Philips Viva Collection (such as the HD4931,
