The correct answer is Switched Mode Power Supply.
- The full form of SMPS is Switched Mode Power Supply.
Key Points
- SMPS or switched-mode power supply
- SMPS or switched-mode power supply is an electronic device that is used to convert AC to DC, AC to AC, DC to DC and DC to AC voltages.
- The circuit consists of a rectifier, voltage regulator transformer, and a filter.
- The input supply is turned On and Off by MOSFETs.
- Fundamentally, different types of circuits work with various kinds of power supplies such as SMPS.
Additional Information
- Difference between Linear Supply and Switch Mode Power Supply
- The linear power supply and Switch mode power supply, both supplies DC power to electrical circuits.
- The crucial factor which differentiates linear power supply and SMPS is the working procedure.
- The Linear power supply converts high voltage AC into the low voltage using a transformer and then converts it into DC voltage.
- While the switched-mode supply converts AC into DC first then transforms that DC voltage into the desired voltage.
