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 […]

How to Design a Buck Converter Circuit: Formulas and Calculations
In this post I have explained the method of designing buck converter circuits by calculating all the required parameters, in order to ensure an optimal performance from these devices. We take the example of IC 555 buck converter typologies, and try to understand the optimizing techniques through equations and manual adjustments, for achieving the most […]
How PNP Transistors Work
In this post I have explained regarding how a PNP transistor works or conducts in response to a fixed biasing voltage and a varying supply voltage, across its base and emitter. The question was put forth by Mr. Aaron Keenan. Question Regarding PNP BJT Working Great information and lots of interesting circuits!I have a question […]
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 an Accelerometer Works
In this post I will try to explain how an accelerometer works and also learn the specifications of a popular accelerometer ADXL335 in detail. If you are a tech enthusiast you would have came across the term called “Accelerometer”. This piece of technology made our smart phones really smart, many common home appliances, automobile, robotics, […]
How Supercapacitors Work
In this post I have explained what a supercapacitor is, how closely similar or different to an ordinary capacitor, where it is used and we will be doing comparison between batteries and super-capacitors to find out which one of them is superior. Let’s understand the basics of an ordinary capacitor. How Ordinary Capacitor Works A […]
