Why is a Full Wave Bridge Rectifier Better Than a Full Wave Center Tap Rectifier? And Their Differences


 Tap Rectifier? And Their Differences

One of the most popular applications of the diode is rectification. The rectifier is a device that converts an alternating current (AC) to pulsating direct current (DC). This pulsating DC has some ripples in it that can remove by using a smoothing capacitor. Different types of rectifiers given below: This article discusses “Why full wave rectifier is better than a full wave center tap rectifier”. In full wave bridge rectifier, the whole input waveform is utilized when compared to half wave rectifier. Whereas in half wave rectifiers only half wave is utilized. The full wave rectifier can be constructed in two ways. One is center tapped full wave rectifier consisting of two diodes and one center tapped secondary winding transformer and the second is a Bridge Rectifier consisting of four diodes namely D1, D2, D3, D4 connected.

Working of Full Wave Bridge Rectifier
The bridge rectifier is constructed by using 4 diodes in the form of a Wheatstone bridge which is fed by a step-down transformer. When a step downed AC supply fed through the bridge, it is seen that during the positive half cycle of secondary supply the diodes D1 and D3 (Shown in below figure) are in forward biased. And the diodes D2 & D4 will not conduct. So the current will pass through the diode D1, load (R), and diode D3. And vice versa during the negative half cycle of secondary input. Generally, an AC input is in the form of the sinusoidal waveform (sin(wt)). The output waveform and circuit diagram is shown below.
