Bridge Rectifier Using Diode Definition: The bridge rectifier circuit is a rectifier circuit, which converts an ac voltage to dc voltage. These circuit generates output of full cycle for input of full cycle. No input cycle is wasted. Bridge rectifier (circuit 1) Input and output waveform of full wave rectifier Bridge rectifier (circuit 2) Input and output waveform of half wave rectifier Working principal: For both circuit Vin is input voltage. Output is Vout. T is step down transformer. n1 is the turn ratio of primary coil and n2 is the turn ratio of secondary coil of transformer. Four diodes (D1, D2, D3, D4) are placed to form bridge (Wheatstone bridge) between for both Vn2 and Vout. Voltage drops at diodes are Vd. R is load resistor. For this bridge structure this rectifier is known as bridge rectifier. Input voltage is applied in primary coil of transformer. This voltage is step down and transferred to secondary coil. Based on the polari...

Precision Rectifier 1. It is basically rectifier circuit, which converts an ac voltage to dc voltage. 2. Then Why it is called as ‘Precision Rectifier’? Because it generates accurate output which is missing in normal rectifier circuit or power-supply rectifier circuit (rectifier circuit using diode). If you don’t know what is a normal rectifier circuit, please visit the link below and watch the video on ‘Rectifier Circuit Design’. 3. Now we have to understand what we mean by accurate output. If you already watched the video on ‘Rectifier Circuit Design’, you will know from both theoretical and practical analysis, we have observed that for practical diode there is a voltage drop (Vd). It varies from 0.4 V to 0.7 V (approximately). This voltage drop effects the output voltage significantly. Sometimes output voltage increases or decreases from the desired level for this voltage drop. But it is not the case for Precision Rectifier. It generates accurate desired output. Thus,...
