Below is a breakdown of the key stages typically found in the schematic.
Dual input, selectable via a manual switch between 110VAC and 220VAC (±15%). s36012 power supply circuit diagram
Converts AC input (typically 110V/220V) to high-voltage DC. Below is a breakdown of the key stages
A gate resistor (10-22Ω) prevents ringing. A pull-down resistor (10kΩ) ensures Q1 is off when U1 is not powered. s36012 power supply circuit diagram
