Whenever you hear the transformerless (AC to DC converter without transformer) supply term, you initially imagine the capacitor-based solution: a high-voltage non-polarized capacitor in series with the mains line, a bridge rectifier, a Zener diode, and a filtering electrolytic capacitor. Such a...
The isolated AC-to-DC flyback converter is the most commonly used power supply type for home and industrial devices. Fear of the main voltage and complexity of calculations cause electronic beginners and enthusiasts to procrastinate DIY such circuits. This project introduces an AC-to-DC flyback...
The maximum power delivery of this power supply is 84W, which means it can handle 7A continuously at 12V output. The transformer can deliver higher currents, however, the educational purpose (hand winding of the transformer) and thermal stress on the switching controller were considered (the...
The most important part of any electronic device is the power supply section. Any instability or malfunction in this part causes the device to stop its operation or show weird behavior. In this article/video, I introduced an AC to DC Flyback Switching power supply that converts 220V-AC to 8V-DC...
Flyback is the most common circuit topology to build galvanically isolated AC to DC or DC to DC converters. Flyback circuit is cheap and relatively easy to manufacture, therefore nowadays the majority of home or industrial appliances are powered using AC to DC Flyback converters. In general, a...
So I tried to make an adaptor that can give me voltage around 9-10 Volts. There are total 5 wires as you can see in the attached image.
I am using a 1000 uF(25V) capacitor parallely after the bridge diodes as said. But the capacitor is heating up and I think the lid/head of the capacitor is...
Hi everybody,
I am not only new here but have little to no clue about electrics/electronics, but a question, where I am hoping to get some ideas/answers.
I have purchased a winch enabling me to pull our boat on a trailer in and out of the water on a ramp. The winch requires 12V and I would like...
