lülitusallikas
Lülitusallikas, also known as a switching-mode power supply (SMPS), is an electronic power supply that uses a switching regulator to convert electrical power efficiently. Unlike linear power supplies that dissipate excess voltage as heat, lülitusallikad rapidly switch components like transistors on and off at high frequencies. This switching action, combined with energy storage components like inductors and capacitors, allows for efficient voltage conversion.
The basic principle involves a high-frequency switch, typically a MOSFET or IGBT, that chops the input voltage.
Lülitusallikad offer significant advantages, including high efficiency, smaller size, and lighter weight compared to linear power
