Rectifier

While making a customized RGB LED set up at our home, basically it was a bunch of addressable 5v LEDs the WS2812, but unfortunately, we didn't have a high current power source to light them up properly. Since there was a lot of them, it required around 9 Amps of current to lighten up at full brightness. This led us to design one Power Supply for this purpose, as well…

A diode is one of the basic components that are commonly used in electronic circuit designs; it can be commonly found in rectifiers, clippers, clampers and many other commonly used circuits. It is a two-terminal semiconductor device that allows the current flow in only one direction, that is, from Anode to Cathode (+ to -) and blocks the current flow in the reverse direction…

Although there are inverters and generators to immediately start the AC power supply whenever there is a power cut but sometime when there is no backup support and we have some critical machines running to perform some important task, it’s a good idea to atleast have an alarm which notify us as soon as power goes off. In this tutorial, we will learn how to make a simple…

In the modern era, almost every household electronics works on Direct Current (DC) but we get Alternating Current (AC) from power generation plants via transmission lines becuase AC can be transmistted more efficiently than DC in lower cost. So every appliance which works on DC has and AC to DC converter circuit. We previously built a 5v cell phone charger which also…

Vishay Intertechnology has today announced that, it is expanding its TMBS surface-mount SMF (DO-219AB) Schottky rectifiers series with 15 more new rectifiers with increased power density and improved efficiency. These new rectifiers are available with a current rating from 1A to 3A, features reverse voltages from 45V to 150V and a forward voltage drop of 0.36V.

There are lots of factories and plants in the world which use a different type of high power motors. Due to the high power consumption, the factories and plants end up paying a high amount of energy bills. To overcome the high power consumption and to increase the efficiency, VFD was introduced four decades ago but the circuitry was not strong enough.

The process of converting alternating current into direct current is rectification. Any offline power supply unit has the circuit for rectification which converts either the AC wall supply into a high voltage DC or stepped down AC wall supply into low voltage DC. The further process will be filtering, DC-DC conversion and etc. So, in this article we are going to discuss…

In this project, we are going to make a TRIAC dimmer circuit for AC Appliances. Here we are not going to use a microcontroller. We have used basic components to complete this task. In this project, we will use Triac to control the brightness of the AC bulb with a IR TV Remote. You can also control Fan speed with your TV remote using this Triac Dimmer circuit.

In this project, we are going to make an AC Voltage Measuring Device using Arduino, which will measure the voltage of Alternating Current Supply at our home.  We are going to print that voltage on serial monitor of Arduino IDE as well as show on the multimeter.

Making a Digital Voltmeter is a lot easy than making an analog one because in case…

The process of converting alternating current into direct current is rectification. Any offline power supply unit has the block of rectification which converts either the AC wall receptacle source into a high voltage DC or stepped down AC wall receptacle source into low voltage DC. The further process will be filtering, DC-DC conversion and etc. So, in this article we are…

Mobile phones generally charge with 5v regulated DC supply, so basically we are going to build a 5v regulated DC supply from 220 AC. This DC supply can be used to charge mobiles as well as the power source for digital circuits, breadboard circuits, ICs, microcontrollers etc.

You can also build 6V DC, 9V, 12V,…
