The right way to measure power supply efficiency must consider four important factors such as: (1) Use the right measuring tools (2) Sample the parameters correctly (3) Use short connections (4) Give some time before taking measurements Use the Right Measuring Tools Efficiency is the ratio of output power to input power. The output power is composed of DC voltage

Switching power supply operation is very different to that of linear power supply. Despite of its complexity, higher bill of material cost and higher parts count, switch mode power supply is still the preferred power supply topology in the market nowadays. The main reason is higher efficiency and higher power density. Higher efficiency simply means that only a small portion

In linear power supply design output regulation is not a question because it is easily done by the linear regulator inserted before the load. Nowadays linear power supply is not anymore widely used. What is drawing more attention now is the switch mode power supply. How switch mode power supply regulates its output is different from what linear regulator does.

Is it worth investing for power supply with low standby power? Come; go with me to explore the answer of this question. Nowadays power supply technology is advancing. There are so many features added that may or may not be useful for end users. It is important for the end users to define his requirements so that to get the
READHow a Switch Mode Power Supply Works? What is the operation of a switch mode power supply? A switch mode power supply works by continuously switching on and off a semiconductor switch. This semiconductor switch is can be a MOSFET or a BJT. The former is more popular than the latter. When the switch turns off, there is no current
