RECTIFIERS & DIODE BRIDGES Definitions A rectifier is an electrical device, mainly consists of diodes, that converts alternating current to direct current or at least to current with only positive value, a process known as rectification. Numbered diodes D 1, D 2, D 3, and D 4 are all the same color, for example, red. During the positive cycle of Vs, point A is positive with respect to B causing diode D1 and D2 to forward bias and D3 and D4 to get reversed biased. The bridge full wave rectifier with a capacitor filter was designed to achieve the specified ripple percentage. The Bridge rectifier circuit is shown in the following figure.
