Munich, Germany, April 10th, 2017 – Switch Mode Power Supplies (SMPS) are needed for a variety of smart energy solutions such as low power lighting controls, audio or thermostat controls and other smart home electronics applications, as well as industrial controls.

In conventional power supplies a linear regulator provides the desired output voltage by dissipating excess electric power in form of heat. Hence, its maximum power efficiency is given by the ratio of input to output voltage. Compared to this linear regulator technology SMPS offer some distinct advantages:

High efficiency
A SMPS regulates its output voltage by switching energy storage elements such as inductors, by means of a transistor changing “on” and “off” states at high frequencies. In this mode of operation, the transistor has a very low resistance in its “on” state, thus enabling the converters to operate with a higher efficiency of up to 90 % depending on load and voltage levels.

Compact and light
For mains input SMPS the necessary isolation is achieved by the built-in transformer which also acts as a mutual inductor for energy storage. Due to the high switching frequency this transformer can be of a much smaller size compared to 50/60Hz iron core types. This results in compact and light weight supplies, enabling applications with high power density

SMPS come in various topologies, which are classified into fundamental categories. Each topology offers specific advantages for certain applications and fit nearly any output voltage. For example, in the low to medium output power range, Flyback SMPS provide a solid and cost effective solution for a wide array of demands. This versatility solves the problem of converting a standard source voltage into a usable, specified output voltage and allows custom-specific solutions.
