What is a Switching Power Supply?

Switching power supplies are designed for high efficiency and small size. They incorporate a switching regulator to convert electrical power efficiently. Switching DC power supplies regulate the output voltage through a process called pulse width modulation (PWM). Using a PWM allows various topologies to be used such as buck, boost, forward converter, half bridge rectifier, or flyback depending on the output power requirements.

The PWM process generates some high frequency noise, but enables the switching power supplies to be built with very high power efficiency and a small form factor. With a good design, a switching power supply can have excellent load and line regulation. They can either step-up or step-down the input voltage to get the desired output voltage. A switching power supply has greater efficiency than linear regulators because the switching transistor dissipates little power when acting as a switch. However, this switching can generate noise which can be lowered by filtering.
