Switching mode drive circuits, often referred to as switch-mode power supplies (SMPS) or simply switching regulators, are electronic power converters that convert direct current (DC) power from one voltage level to another. They achieve this by rapidly switching a power semiconductor device, such as a transistor or MOSFET, on and off. This switching action creates a pulsed waveform, which is then filtered and regulated to produce the desired output voltage. Unlike linear regulators, which dissipate excess energy as heat, switching regulators are significantly more efficient, typically ranging from 70% to over 90%.
The core principle involves storing energy in an inductor or capacitor during the "on" state of the
Switching mode drive circuits are ubiquitous in modern electronics due to their efficiency and compact size.
