If , trace backward through the bridge rectifier to the fuse.

Looks like a power supply. From the label I'm thinking it's a 90vdc supply for a DC motor. ... Induction cooker PCB. Electronics Craftsman

The CHK-V9.04G circuit diagram is a complex schematic that illustrates the various components and subsystems of the device. The diagram is typically divided into several sections, each representing a specific functional block or module. These sections may include: chk-v9.04g circuit diagram

: A Metal Oxide Varistor (MOV) clamps transient voltage spikes coming from the mains power grid.

Linear regulation and LDOs

A series of transistors (e.g., S8050/S8550) that amplify the MCU signal to trigger the IGBT gate. Common Faults and Troubleshooting

Typically rated at 3.15A/250V. It breaks the circuit during a catastrophic short. If , trace backward through the bridge rectifier to the fuse

Understanding this diagram is critical for technicians troubleshooting issues like failure to power on, improper cooking, or, more commonly, damage to the IGBT (Insulated Gate Bipolar Transistor). 1. Overview of the CHK-V9.04G Board Layout

: A sensor placed in the center of the induction coil monitors the temperature of the cookware to prevent dry-heating or overheating. The diagram is typically divided into several sections,
