Power Supply Circuits

In this article I will comprehensively discuss how to make customized transistorized voltage regulator circuits in fixed modes and also variable modes. All linear power supply circuits which are designed to produce a stabilized, constant voltage and current output fundamentally incorporate transistor and zener diode stages for getting the required regulated outputs. These circuit projects […]

In this post I have explained 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, or P-channel MOSFETs back to back in series with the specified voltage line. What is a Bidirectional Switch A bidirectional power switch (BPS) is […]

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 create a perfectly optimized transformer for a given application. The post presents a detailed explanation regarding how to calculate and design customized ferrite core transformers. […]

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 manufacturing cost, simpler design and uncomplicated implementation. The low current DCM version of flyback converters which include output specification lower than 50 watt are more […]

I have explained comprehensively how to build a boost converter circuit for converting a low level DC voltage inputs to a higher level DC voltage outputs. I have furnished all the required calculations s that you can design a customized boost converter circuit. How a Boost Converter Works A boost converter is a kind of […]

A step down transformer is a device which reduces a higher AC potential to a lower AC potential as per its winding ratio and specifications. In this article we are going to discuss how to design and construct a basic step down transformer which are typically applied in mains-operated power supplies. Introduction This will likely […]
