: A large Bridge Rectifier converts AC to DC. You’ll see a massive filter capacitor (typically 5µF/400V) that smooths this high-voltage DC. The Resonant Tank (The "Heart") :
. As a "universal" or replacement PCB, it is designed to manage high-power electromagnetic induction, typically supporting units between 1800W and 2000W Functional Breakdown of the Circuit chk-v9.04g circuit diagram
This is the heart of the supply. The main switching transistor (typically an STP10NK60Z or IRF840) is driven by a PWM controller. From the diagram, V9.04G usually employs a —often a 3844B or a proprietary DIP-8 chip. : A large Bridge Rectifier converts AC to DC
