A typical Switched Mode Power Supply comprises a front-end AC-DC rectifier, generating an unregulated DC input voltage for the switching circuit. A high-frequency PWM (Pulse Width Modulation) drive transforms this DC output into a pulsating square wave through a MOSFET/IGBT switching device. A high-frequency transformer then isolates, steps down, and converts this square wave DC into square wave AC output. Finally, the output is rectified and filtered to produce a smooth, ripple-free regulated DC output. Closed-loop feedback control ensures precise output regulation, intrinsic protection against overload and short circuit.
