Full Form of SMPS | SMPS Full Form | What is SMPS | About SMPS
Full Form of SMPS is Switched-Mode Power Supply: SMPS stands for Switched-Mode Power Supply. It’s an electronic power provide that uses a switching regulator to convert electrical power with efficiency. It’s additionally called switching Mode Power supply. It’s power supply unit (PSU) typically utilized in computers to convert the voltage into the pc acceptable range.
This device has the power handling electronic parts that converts power with efficiency. Switched Mode Power provide uses an excellent power conversion technique to scale back overall power loss. The SMPS device uses shift regulators that switches the load current on and off to control and stabilize the output voltage. The typical of the voltage between the off and on produces the suitable power for a device.
According to Wikipedia:
A switched-mode power supply (switching-mode power supply, switch-mode power supply, switched power supply, SMPS, or switcher) is an electronic power supply that incorporates a switching regulator to convert electrical power efficiently. Like other power supplies, an SMPS transfers power from a DC or AC source (often mains power) to DC loads, such as a personal computer, while converting voltage and current characteristics. Unlike a linear power supply, the pass transistor of a switching-mode supply continually switches between low-dissipation, full-on and full-off states, and spends very little time in the high dissipation transitions, which minimizes wasted energy. Ideally, a switched-mode power supply dissipates no power.
Voltage regulation is achieved by varying the ratio of on-to-off time. In contrast, a linear power supply regulates the output voltage by continually dissipating power in the pass transistor. This higher power conversion efficiency is an important advantage of a switched-mode power supply. Switched-mode power supplies may also be substantially smaller and lighter than a linear supply due to the smaller transformer size and weight. Switching regulators are used as replacements for linear regulators when higher efficiency, smaller size or lighter weight are required. They are, however, more complicated; their switching currents can cause electrical noise problems if not carefully suppressed, and simple designs may have a poor power factor.
