Introduction to Switching Power Supply
Switching power supply, also known as switch – mode power supply (SMPS), is a type of power supply that uses switching regulators to convert electrical power efficiently. Unlike linear power supplies, which dissipate excess power as heat, switching power supplies work by rapidly switching the input voltage on and off. This process allows them to achieve high efficiency, often above 80%, and they are widely used in various electronic devices such as computers, mobile phones, televisions, and industrial equipment. They offer advantages like compact size, light weight, and a wide range of output voltages, making them an essential component in modern electronics. Switching Power Supply
