disadvantages of full wave bridge rectifier

Disadvantages of a bridge rectifier Two or more diodes are required in case of a bridge rectifier, as a full-wave rectifier uses two diodes whereas a bridge rectifier uses four diodes. Two diodes in series conduct at a time on alternate half-cycles. It is because, in this case, the two diodes are connected in series and offer double voltage drop due to their internal resistance. A bridge rectifier makes … Half wave rectifier cannot provide as much efficiency in compare to bridge rectifier because it only convert positive half cycle into DC. 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. A rectifier circuit whose transformer secondary is tapped to get the desired output voltage, using two diodes alternatively, to rectify the complete cycle is called as a Center-tapped Full wave rectifier circuit.

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. The full-wave rectifier can be designed by using with a minimum of two basic diodes or it can use four diodes based on the topology suggested. What are the advantages and disadvantages of a full-wave rectifier circuit over a bridge-rectifier circuit? The transformer is center tapped here unlike the other cases. A full wave bridge rectifier is a type of rectifier which will use four diodes or more than that in a bridge formation. The reason is that a half wave rectifier makes use of only one half of the input signal. Disadvantages of bridge rectifier: In this type, two extra diodes are used. Another disadvantage of bridge rectifier is that the load resistor RL and the supply source have no common point which may be earthed. Peak Inverse Voltage of Center Tapped Full Wave Rectifier. Save my name, email, and website in this browser for the next time I comment. The output voltage is half of the secondary voltage, as each diode utilizes only one half of the transformer secondary voltage. The only advantage of bridge rectifier over center tapped full wave rectifier is the reduction in cost. The voltage drop across diodes increases four times than that of centre tap full wave rectifier. It has prons and cons, they are as follows :: Advantages: * Step Down Transformer is not required. Bridge rectifier circuit is more complex than half-wave. Full wave rectifier finds uses in the construction of constant dc voltage power supplies, especially in general power supplies. 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 You Need To Know About Bridge Rectifier Your email address will not be published. But diodes being cheaper than a center tap transformer, a bridge rectifier are much preferred in a DC power supply. Disadvantages. The rectification efficiency of full-wave rectifier is double of that of a half-wave rectifier. For a full wave rectifier, the maximum possible value of rectification efficiency is 81.2 % while that half wave rectifier is 40.6 %. Hence not recommended for small voltage rectification. It contains fort diodes connected to form bridge. The PIV (peak inverse voltage) of a diode used  twice that of the diode used in the half wave rectifier, so the diodes used must have high PIV. Full wave rectifier advantages and disadvantages. The main difference between center tap and bridge rectifier is in the number of diodes involved in circuit. Disadvantages of Full Wave Bridge Rectifier It needs four diodes. This poses a problem when low voltages are required. Efficiency is double for a full wave rectifier. The features of a center-tapping transformer are − 1. This poses a problem when low voltages are required. Bridge rectifier is often in many electrical devices to control the AC source to a DC source by the process of rectification . Advantages and Disadvantages of Full Wave Rectifier Over Half Wave Rectifier Advantages. The centre-tapped rectifier is more expensive than half-wave rectifier and tends to occupy a lot of space.
