In the previous article I explained about ripple factor in power supply circuits, here we continue and evaluate the formula for calculating ripple current, and consequently the filter capacitor value for eliminating the ripple content in the DC output. The previous post explained how a DC content after rectification may carry the maximum possible amount […]

Notch Filter Circuits with Design Details
In this article I will provide a detailed explanation regarding how to design notch filters with precise center frequency and for maximum impact. Where Notch Filter are Used Notch filter circuits are normally used for suppressing, nullifying, or cancelling a particular range of frequencies in order to avoid an annoying or unwanted interference within a […]
How Logic Gates Work
In this post I will comprehensively explain what logic gates are and its working. We will be taking a look at the basic definition, symbol, truth table, Multi input gates, we will be also constructing transistor based gate equivalents and finally we will take an overview on various relevant CMOS ICs. What are Logic Gates […]
How to Select MOV – Explained with a Practical Design
MOVs or metal oxide varistors are devices designed for controlling mains switch ON surges in electrical and electronic circuits. Selecting an MOV for a particular electronic circuit might require some consideration and calculation, I have explained the procedures here. What are MOVs Metal oxide varistors or simply varistors are non-linear surge suppressor devices which are […]
How to Use Transistors
If you have understood correctly, how to use transistors in circuits, you might have already conquered half of electronics and its principles. In this post we make an effort in this direction. Introduction Transistors are 3 terminal semiconductor devices which is able to conduct relatively high power across their two terminals, in response to a […]
How to Compare IGBTs with MOSFETs
In this post I have explained the main differences between an IGBT and a MOSFeT device. I have explained more about the facts from the following article. Comparing IGTB with power MOSFETs The insulated-gate bipolar transistor features a voltage drop which is significantly low when compared to a conventional MOSFET in the devices which have […]
