Basic Power supply circuits Part 1

Posted on

To understand power supply circuits, we need to understand rectifiers. A rectifier converts AC or alternating current to DC direct current. Rectifiers are used in Power supply circuits which we will discuss in detail. The process of converting AC to DC is called Rectification. Half wave rectification. It requires only single diode. Only positive cycle […]
