A switched-mode power supply (SMPS), also called switching-mode power supply, switch-mode power supply, switched power supply, or simply switcher, is an electronic power supply that incorporates a switching regulator to convert electrical power efficiently.
A switching power supply, or SMPS, is an electronic power supply that incorporates a switching regulator to efficiently convert electrical power. It is used to provide a stable output voltage from a varying input voltage.
An SMPS, like other kinds of power supplies, converts current and voltage characteristics while transferring power from an AC or DC source (often mains power; see AC adapter) into DC loads, like a personal computer.
The industry drive toward smaller, lighter and more efficient electronics has led to the development of the Switch Mode Power Supply (SMPS). There are several topologies commonly used to implement SMPS.
SMPS stands for switch mode PSU. In such a device, power handling electronic components are continuously switching "on" and "off" with high frequency in order to provide the transfer of electric energy via energy storage components (inductors and capacitors).
SMPS stands for switched mode power supply. It is known by a wide range of names like power supply, supply unit, regulator, or switcher in an electronic power supply.
Switched-mode power supplies (SMPS), sometimes referred to as switch mode power supplies, have become the workhorse of efficient power conversion, taking a mains voltage AC input and converting it down to a low voltage DC output.
