Filters are commonly used in power and audio electronics to reject unwanted frequencies. There are many different types of filters used in electronic circuit designs based on the application but the underlying concept of all of them is the same, that is to remove unwanted signals. All these filters can be categorized into two types- Active filters and passive filters. The…
It’s the moonshot of our time. From sensors to artificial intelligence (AI), the classic electronics supply chain has formed a collaborative matrix dedicated to making autonomous vehicles safe. To that end, there is much to be done in hardware and software development to ensure drivers, passengers, and pedestrians are protected. While machine learning and AI have a role to…
We all know that life is sustained on earth because of the sun as it provides sufficient heat energy to keep the earth warm. This energy is delivered by the sun in the form of Electromagnetic radiation which is usually called solar radiation. Some of the radiation is beneficial to humans while another radiation is harmful to all life.

We all know about an inverter - it is a device which converts DC into AC. And we previously learned about Different types of inverters and built a single-phase 12V to 220V inverter. A 3 Phase Inverter converts the DC voltage into a 3 Phase AC supply. Here in this tutorial, we will learn about the Three-Phase Inverter and its working, but before going any further, let…
As most of the types of equipment we use today are being automated with state-of-the-art technologies, the advent of autonomous vehicles is no longer a surprise. Various mechanical features in conventional cars are being transformed into an automatic function. Consequently, today, semi-autonomous cars have become more ubiquitous than ever.

The durability and dependability of an electronic circuit are highly dependent on how well it is designed considering all odds, which could practically occur when the product is actually in use. This is particularly true for all power supply units like AC-DC Converters, or SMPS Circuits because they are connected directly to the AC mains and a varying load which makes them…
When you want to design bipolar transistor circuits you need to know how to bias them. Biasing is applying electricity to a transistor in a specific way to make the transistor perform the way you want it to. There are mainly five classes of Amplifier - Class A, Class B, Class AB, Class C and Class D. In this article we will focus on biasing the transistor in a common emitter…
During a common operation & maintenance practice, I have noticed that in various plants for changing the direction of Low Tension motors that are below 15 KWs, the phase sequence inside the panel (the terminals below the power contactor or below thermal overload relay) is normally changed as shown in the picture above.

Artificial Intelligence is one of the greatest discoveries in the field of science, and it has begun to become more prevalent than ever worldwide. Scientists’ curiosity about how more can be done with this technology is showing no signs to recede. Is it time, already, to get frightened of the potential of Artificial Intelligence to become smarter than us? Artificial…
The Grid Dip Meter (GDM) or the Grid Dip Oscillator (GDO) is an electronic instrument used in measurement and testing of radio frequency circuits. It is basically an oscillator with an exposed coil and oscillation amplitude readout. It has three main functions:
Measuring the resonant frequency of an LC resonant circuit, a Crystal/Ceramic resonator, or an Antenna,…
Hello again Friends, I have been sharing many case studies related to Electrical Maintenance, hope you are enjoying them and they are useful during your plant operations. My motto behind sharing my experience is that the problem faced in one plant should not be repeated to other Plant. That being said. Let’s get into today’s case studies.

Air pollution, we all know is a major global issue that is causing premature deaths and illnesses throughout the world. Each one of us intentionally or unintentionally is leaving the carbon footprints and posing environmental hazards. The vehicles like cars, two-wheelers that we use for commuting are among the major contributors to the environment pollution. In…
