In this post I have explained the response of inductors to DC and AC voltages as well as when applied with capacitors which is often used as a complementing part with an inductor. Properties of Inductor Inductors are known for their property of storing electrical energy in them in the form of magnetic energy. This […]

Difference Between Alternating Current(AC) and Direct Current(DC)
In this post we try to investigate the mains differences between alternating current (AC) and direct current (DC). The word AC and DC are pretty common with electronics and we all come across it while developing or dealing electronic circuit designs. Overview Though the terms are very ordinary with the field, many noobs become confused […]
220V AC to 56V DC SMPS Circuit for 48V Battery Charging
In this article we will try to understand how to build a 220V AC to 48 V DC SMPS circuit for charging all types of 48V batteries, using the nice little IC IR2153. However, since 48V battery will require a 56V DC, so we will rather discuss a 220V to 56 V DC battery charger […]
100A AC Load Monitoring Circuit using Arduino, Watt Limit, LCD, Alarm, Auto Shutdown
In this project we are going to make one very useful grid power protection circuit. This will be like a power guard system which we can use in homes or apartments to monitor the wattage of the load and also to cut off the load automatically if it starts taking too much wattage, more than […]
Password Controlled AC Mains ON/OFF Switch
In this post I will show how to construct a password based mains ON/OFF switch circuit, which can turn ON and OFF the AC mains supply, only when correct password is entered. This prevents the danger of electrocution of the technician who might be currently working with the high voltage lines and equipment. Password Protection […]
Mains AC Short Circuit Breaker/Protector – Electronic MCB Circuit
In this post I will try to explain the making of a simple 220 V, 120 V AC mains short circuit breaker using an SCR and a triac combination, (researched and designed by me). The circuit is an electronic version of the normal main circuit breaker MCB units that we use in our homes. Note: […]
