Power Electronics

In this category we fundamentally discuss power electronic principles related to switch mode power supplies.

The subject basically includes theories involving solid state power supplies built with switching semiconductor devices like mosfets and IGBTs.

Here we mostly focus on SMPS converters which are used for converting mains AC to low DC using switch mode technology and ferrite based transformers.

Power electronics was developed to ensure higher efficiency in converter designs in terms of cost, weight and consumption.

Thus we can see why SMPS based systems are compacts and lighter in weight than the conventional iron cored converters, and these are additionally very energy efficient since SMPS circuits waste very little power while operating.

However handling power factor correction becomes  a major issue while designing power electronic circuits, and in this segment we also have a detailed article regarding the correct implementing of PFC in SMPS circuits.
