The complete circuit diagram is structurally divided into five core functional modules: Power Management Unit (PMU) Induction Cooker Circuit Design
The CHK-V9.04G circuit diagram has various applications in different industries, including:
After the filter stage, the AC voltage feeds directly into a high-current . The rectifier converts the AC voltage into a pulsating DC output. This output is smoothed by a massive high-voltage DC filter capacitor (typically 5µF, 400V or 450V) working alongside an induction line filter inductor to create a stable high-voltage DC rail (approx. 300V–310V DC) that powers the primary heating coil.
