Abstract: An optocoupler is a widely used electrical control switching device that falls under the direct-current (DC) on/off category from a functional perspective. The datasheet for optocouplers ...

Abstract: In DC/AC inverters, multi-level inverters have emerged as the industry standard and are essential for numerous industrial applications. Multi-level inverters (MLIs) are becoming more common ...

The isolated AC-to-DC flyback converter is the most commonly used power supply type for home and industrial devices. The isolated AC-to-DC flyback converter is the most commonly used power supply type ...

In this article/video, the author introduces an AC-to-DC flyback switching power supply that converts 180V-260VAC to 12VDC. The most essential part of any electronic device is the power supply unit.

In this post I will try to gain some insight into the electronics of a cheap PWM Power MOSFET Module. The module under the spotlight is the pretty common FR120N MOSFET Control Module which is a simple ...

In some places, especially in developing countries like ours, sudden fluctuations in the mains voltage are quite common. This sometimes causes a serious damage of electrical appliances like television ...

I have selected ESP8266(ESP-01) Chip which is the smallest microcontroller that comes with default wifi connectivity and also we can design a small PCB using this ESP8266 Chip. The next main component ...
