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 core element of any electronic device is the power supply. Any instability or malfunction of the power supply causes the device to malfunction or demonstrate weird behavior. In some sensitive applications, we need a dual voltage-rail power supply to prepare a high current and low noise...
