The lead-Acid battery is one of the most common batteries used all over the world. In this article, I’ll discuss these lead-acid battery charging methods and we’ll see which will be the most suitable for our battery. I hope this article will be helpful to you. Before we start talking Read more…
We know that the PWM signal is very easy to generate and we can control DC loads using this PWM signal. If we could use the PWM pulse to drive AC loads, the control circuit would become very easy. This is why many people look for PWM based driver circuit Read more…
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 pulse with a NE555 timer IC. What is 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…
Measuring current sometimes become 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 about DC current measurement techniques and different circuits for this purpose. DC current sensing techniques: Based on different circuit configuration Read more…
Measuring high voltage AC is not safe just with resistor voltage divider. Or sometimes, we can not connect one terminal to GND of the measuring circuit. Sometimes, we need to measure a floating high voltage. In this article, we are going to learn how to do that floating high voltage Read more…
