From hobbyists to professionals transformerless power supply is one of the common power supply design everyone wants to do. This type of power supply has both advantages and disadvantages. In this article, I’ll discuss in detail this subject and will see several methods with calculations. So let’s start our “Transformerless Read more…
We know that the PWM signal is very easy to generate using micro-controllers 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 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…
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…
