Full Wave Rectifier With And Without Filter In Telugu circuit & Manual : https://drive.google.com/drive/folder... A full-wave rectifier is an essential circuit in power supplies and electronic devices, converting an AC (alternating current) input into a DC (direct current) output. The performance and characteristics of the output depend significantly on whether a filter is used or not. Let's explore the functioning of a full-wave rectifier with and without a filter. Full-Wave Rectifier Without Filter Circuit Diagram A basic full-wave rectifier circuit without a filter typically consists of: Transformer: Steps up or steps down the AC voltage to the desired level. Diodes: Four diodes arranged in a bridge configuration for full-wave rectification. Operation During the positive half-cycle of the AC input, two diodes conduct and allow current to pass through the load in one direction. During the negative half-cycle, the other two diodes conduct, allowing current to pass through the load in the same direction as during the positive half-cycle. Output Characteristics The output voltage is a pulsating DC, which means it fluctuates between zero and the peak value of the rectified signal. There is significant ripple (AC components) in the output, making it unsuitable for sensitive electronic devices without further processing. Waveform The output waveform is a series of positive half-cycles of the AC input, with no negative half-cycles. Full-Wave Rectifier With Filter Circuit Diagram In a full-wave rectifier with a filter, a capacitor (and sometimes an inductor) is added to the circuit to smooth out the fluctuations in the output voltage. Transformer: Steps up or steps down the AC voltage to the desired level. Diodes: Four diodes arranged in a bridge configuration for full-wave rectification. Filter Capacitor: Connected across the load to smooth out the rectified output. Operation: The diodes operate as in the unfiltered rectifier, but the capacitor charges during the peaks of the rectified output and discharges during the troughs. This charging and discharging action smooths out the pulsations in the output voltage. Output Characteristics: The output voltage is much smoother and has less ripple compared to the unfiltered rectifier. The DC output is more stable and suitable for powering electronic circuits. Waveform : The output waveform is a smoother DC signal with reduced ripple, approximating a steady DC voltage. #telugu #rguktongole #ece #rgukt #edc #fullwaverectifier
