switching power supplies

A switching power supply converts electrical energy from an AC outlet into a stable DC voltage needed by electronic devices. Unlike traditional power supplies that use large transformers and resistors, switching power supplies quickly turn the power on and off at high speeds, controlling the energy transfer efficiently. This process reduces waste, generates less heat, and allows for a compact, lightweight design. They're commonly used in computers, chargers, and many electronics because they provide reliable, adjustable power while maintaining high efficiency.
