Yes, the AC load can be dimmed or controlled using the PWM technique. PWM is Pulse-Width Modulation which is mostly used in DC circuits to control DC loads but if it is configured correctly, it can be used in AC load. In this article, we are going to see how Read more…
This is a small article with a basic feature of LM555 or NE555 timer IC. This timer IC is very common and can be used in different circuits in different operating configurations. In this article, we are going to generate a PWM signal using NE555 timer IC. What is PWM Read more…
For large inductive AC loads, a soft starter is a very important circuit. A soft starter reduces the initial power supply to the load and potentially reduces electrical and mechanical shock to the device. Specially motors. The soft starter also reduces the spike in the initial current to any kind Read more…
A dimmer circuit is one of the basic circuits in power electronics people want to make. In this article, let’s learn how to make an AC dimmer circuit. In this project, we will use a PIC 12F675 microcontroller and a TRIAC as the switching device. Let’s start our AC dimmer Read more…
Data Logger is a device that records data periodically with time and date which can be used in the analysis of the system. In this article, we’ll make a solar data logger. We will use Arduino UNO for this project. A memory card, Real-Time Clock (RTC) will be used too. Read more…
When you are working with electronics, especially power electronics you must have to measure line frequency. But in most cases, people do not have a frequency meter. If you knew how to make a frequency meter in a very easy way, you would make one for yourself. Here in this Read more…
Let’s make an Ammeter. Yes, in this article we are going to make an Ammeter for DC circuits. After reading this article you’ll be able to make one for yourself too. I hope it will help you a lot. So let’s start our DC Ammeter with PIC16F73 microcontroller. What is Read more…
In this article, we will discuss DC Current measurement using Shunt. Measuring current sometimes becomes very necessary in electronics circuits. We can measure DC current using current sensors or by using simple shunt resistors. In this article, I’m going to discuss DC current measurement techniques and different circuits for this Read more…
