12V DC to 220V DC Boost Converter Circuit
In this article I have explained a very simple method of acquiring 220V DC from a 12V DC source. The idea utilizes inductor/oscillator based boost topology with the help of the IC 555. Circuit Operation Now let us learn more about this simple 12V to 220V DC boost converter circuit, which is built around IC […]
5V, 12V Buck Converter Circuit SMPS 220V
This step down buck converter will convert a 220V AC input from mains supply to 5V or 12V or 24V DC with 90% efficiency. The proposed buck converter is an SMPS circuit using the IC VIPer12A from STMicroelectronics. The circuit uses negligible number of external components yet is able to operate directly from mains AC input. The Buck […]
220V Operated LED Flasher Circuit using Triac
The following triac/diac based mains operated LED flasher circuit which is actually an astable multivibrator circuit utilizes only a diac and resistor arrangement for implementing interesting wig wag flashing of two LEDs. The simple 220V flasher circuit was shared with me by Mr.Vineesh, who is one of the keen followers of this blog. I would […]
