Switch-mode Power Supplies [REAL • 2024]

The primary function of an SMPS is to transfer power from a source (AC or DC) to a load while regulating voltage and current. The process generally follows these steps:

For AC-to-DC conversion, the input voltage is first rectified and filtered. Switch-Mode Power Supplies

A "chopper" (switching transistor) converts the DC voltage into a high-frequency pulse train. The primary function of an SMPS is to
