During the positive half cycle of the supply, diodes D1 and D2 conduct in series while diodes D3 and D4 are reverse biased and the current flows through the load During the negative half cycle of the supply, diodes D3 and D4 conduct in series, but diodes D1 and D2switch “OFF” as they are now reverse biased. I L = rms value of load current. The rectifying efficiency of a full wave rectifier(full bridge rectifier) when the forward diode resistance is zero is approximately 81.06%. The main advantages of a full-wave bridge rectifier is that it has a smaller AC ripple value for a given load and a smaller reservoir or smoothing capacitor than an equivalent half-wave rectifier. This peak voltage assumes no load, whether a single diode is used or a bridge rectifier, plus capacitor of sufficient value to remove any AC ripple. Disadvantages of half wave rectifier.2. The current flowing through the load is the same direction as before. In center tapped rectifier each diode uses only one-half of the transformer secondary voltage, so the DC output is comparatively small, also it is difficult to locate the center-tap on secondary winding of the transformer and the diodes used must have high Peak-inverse voltage. Bridge Rectifier Circuit Analysis: In the bridge rectifier circuit, among four diodes two diodes conduct during one half cycle. Visualizing D1 and D2 as shorts (ideal model), as in Figure (a), you can see that D3 and D4 have a peak inverse voltage equal to the peak secondary voltage.
