Switch Mode Power Supply (SMPS) Topologies

Scheduling Switch-Mode Power Supply Noise for Real-Time Systems

A Switch-Mode Power Supply (SMPS) is invaluable in its ability to efficiently convert energy, which allows digital logic circuits to operate at the most efficient voltage based upon power and timing parameters, saving power and energy. However, an SMPS introduces noise into the system. Some real-time computing systems contain hardware resources that are rivalrous in nature. These are groups of ...

Single Stage Techniques for Power Factor Correction

Medium and high power switch mode power supplies SMPS (>500W) used in telecommunications stations are normally based on the full-bridge DC-DC converter with isolation transformer. According to the transistors states, the full-bridge converter allows four different switching sates which can be used to control the output voltage of the SMPS, and to perform the power factor corrector (PFC) functio...

Theoretical Formulation for Reduce Dna Separation Time Using High Efficiency Switch Mode Power Supply (smps) of a Gel Electrophoresis Unit

250 W flyback SMPS design for a big size CTV

This paper presents the design criteria, procedure and implementation of an AC-DC Flyback Switch Mode Power Supply (SMPS) which provides 250W rated average power to a big size Colour Television (CTV) Set with a DVD player. A novel technique is developed to keep the Stand-By power consumption of Flyback SMPS under 1W and a boost type of Active Power Factor Correction (Active PFC) preconverter is...

IPASJ International Journal of Electrical Engineering (IIJEE)

Volume 2, Issue 5, May 2014 Page 16 Abstract The switch mode power supply(SMPS) has been achieved the high power density and high performance by developing the power semiconductor devices such as IGBT, BJT, MOSFET, and GTO etc. SMPS has the capacity to handle the variable loads and variable input voltage. The efficiency, weight and size of power supplies are a great area of concern for the powe...
