This full-wave bridge rectifier uses four diodes. Full wave operation van be obtained even without the Centre tapped transformer in bridge rectifier. Average and RMS Value of bridge rectifier, Peak Inverse Voltage (PIV) of bridge rectifier, Transformer Utilization Factor of bridge rectifier, Advantage of center-tap Full-wave rectifier. Although the full wave rectifier circuit requires more diodes than a half wave rectifier circuit, it has advantages in terms of utilising both halves of the alternative waveform to provide the output. Peak Inverse Voltage of Center Tapped Full Wave Rectifier. It requires four semiconducting diodes. PIV rating of the diode is higher. Disadvantages of Full Wave Rectifiers. The only advantage of bridge rectifier over center tapped full wave rectifier is the reduction in cost. Your email address will not be published. The main disadvantage of a bridge rectifier is that it needs four diodes, two of which conduct in alternate half-cycles. The circuit diagram given below shows the instant when the secondary voltage attains its maximum positive value. Your email address will not be published. The rectification efficiency of full-wave rectifier is double of that of a half-wave rectifier. The tapping is done by drawing a lead at the mid-point on the secondary winding. The centre-tapped rectifier is more expensive than half-wave rectifier and tends to occupy a lot of space. Because of this the total voltage drop in diodes becomes double of that in case of centre-tap rectifier, losses are increased and rectification efficiency is somewhat reduced. The bridge rectifier is constructed by using 4 diodes in the form of a Wheatstone bridge which is fed by a step-down transformer. This leads to poor voltage regulation. The transformer is center tapped here unlike the other cases. Half wave rectifier’s peak output voltage are same as input peak output voltage but it waste many voltages. The ripple factor is much less than that of half wave rectifier. Because of this the total voltage drop in diodes becomes double of that in case of centre-tap rectifier, losses are increased and rectification efficiency is somewhat reduced. The main difference between bridge rectifier and center tapped full wave rectifier is that, bridge rectifier produces almost double the output voltage using the same secondary voltage. What are the advantages and disadvantages of a full-wave rectifier circuit over a bridge-rectifier circuit? Disadvantages of full-wave rectifier: More complected than half-wave rectifier. because two diodes are connected in series create a double voltage drop due to internal resistance. Disadvantages of Full Wave Bridge Rectifier It needs four diodes. A bridge rectifier makes … Advantages and Disadvantages of Full Wave Rectifier Over Half Wave Rectifier Advantages. As we all know the basic principle of the diode it can conduct the flow of … The Full Wave Bridge Rectifier It is because, in this case, the two diodes are connected in series and offer double voltage drop due to their internal resistance. The ripple voltage is low and of higher frequency in case of full-wave rectifier so simple filtering circuit is required. The circuit of a bridge rectifier is complex when compared to a half-wave rectifier and center-tapped full-wave rectifier. The only disadvantage of bridge rectifier over center tapped full wave rectifier is in the cost involved in the set up. This creates a problem when low DC voltages are required. In other words, the overall applied ac input signal is converted into pulsating dc by the full wave rectifier. A full wave rectifier is a circuit that has the ability to pass both the halves of the applied input signal.
