In this post we learn about MOSFET bidirectional power switches, which can be used for operating a load across two points bidirectionally. This is simply done by connecting two N-channel, […]
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.
According to the definition given in Wikipedia an electrical transformer is a stationary equipment that exchanges electrical power across a couple of closely wound coils, through magnetic induction. A constantly […]
Calculating ferrite transformer is a process in which engineers evaluate the various winding specifications, and core dimension of the transformer, using ferrite as the core material. This helps them to […]
A flyback configuration is the preferred topology in SMPS application designs mainly because it guarantees complete isolation of the output DC from the input mains AC. Other features include low […]
A couple of simple boost converter circuts are explained in this post, whch can be build and applied by any hobbyists for their own specific requiremenet. What is a Boost […]
In this post we try to diagnose a burnt SMPS circuit and try to troubleshoot and repair the circuit. The shown unit is a cheap readymade Chinese make SMPS circuit. […]
