The rectifier bridge is a simple and common circuit used in electronic devices to convert AC power to DC power. It consists of four diodes that allow the positive half-cycle of AC power to flow through two diodes and the negative half-cycle to flow through the other two, resulting in a DC output with an AC ripple. To obtain a suitable voltage level for electronic circuits, a step-down transformer is used, and a capacitor is connected at the output to smooth the voltage waveform. The rectifier bridge is widely used in power supplies for electronic devices, and understanding its working principle is essential for electrical engineers and hobbyists alike.
