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. The size of the transformer is small for the same dc power output as obtained from full wave rectifier. The full wave rectifier has some basic advantages over the half wave rectifier. The main difference between center tap and bridge rectifier is in the number of diodes involved in circuit. It has many advantages over a center-tap and half-wave rectifier, as given below. As we all know the basic principle of the diode it can conduct the flow of … Advantages and Disadvantages of Center Tapped Full Wave Rectifier. The bridge rectifier is a full-wave rectifying circuit that utilizes both the cycles for rectification. Advantages and Disadvantages of Centre Tap Full wave Rectifier. They are. It requires four diodes for operation, thus, circuit components requirements in case of the bridge rectifier is more than that of centre tap rectifiers. 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. FULL-WAVE BRIDGE RECTIFIER Advantages Disadvantages A Peak Inverse Voltage rating of only > Vp is needed Four diodes are needed For a given C, ripple voltage and peak diode current will be less than in the case of the half-wave rectifier There are now two diode drops during each half cycle Disadvantages: In it the four diodes are used that increases the cost of making it. The ripple voltage is low and of higher frequency in case of full-wave rectifier so simple filtering circuit is required. A Rectifier circuit that rectifies both the positive and negative half cycles can be termed as a full wave rectifier as it rectifies the complete cycle. Disadvantages of Half Wave Rectifier. SCHEMATIC DIAGRAM . For a full wave rectifier, the maximum possible value of rectification efficiency is 81.2 % while that half wave rectifier is 40.6 %. Diodes with high PIV rating are to be used. The transformer is less costly as it is required to provide only half the voltage of an equivalent centre-tapped transformer used in a full wave rectifier. The only difference between this circuit and another circuit of the full wave with center-tapped transformer is that here the diodes are connected in bridge topology with no necessity of the center-tapped transformer in it. Regulation of Full Wave Rectifier Merits and Demerits of Full-wave Rectifier Over Half-Wave Rectifier Merits – let us talk about the advantages of full wave bridge rectifier over half wave version first. This creates a problem when low DC … Disadvantages of Full wave Rectifier: Output voltage is half of the full secondary voltage. ILLUSTRATION . What are the advantages and disadvantages of a full wave bridge rectifier compared to a center tap full wave? Economical: It is low in cost. Low rectification Efficiency: The rectification efficiency of Half wave rectifier is quite low, i.e. The efficiency of the bridge rectifier is higher than the efficiency of a half-wave rectifier. Circuit Diagram: A half-wave rectifier delivers only half the available energy in an AC wave. These advantages are mentioned below: 1) The rectification efficiency of full wave rectifier is double than the half wave rectifier because it converts both the cycles of AC to DC. The rectification efficiency of full-wave rectifier is double of that of a half-wave rectifier. The reason is that a half wave rectifier makes use of only one half of the input signal. The ripple factor is much less than that of half wave rectifier. To use a bridge rectifier, a low level filter is required, so thus reducing the cost of it. The construction of a full wave rectifier can be made in two types. Efficiency is double for a full wave rectifier. Design of a bridge rectifier circuit Advantages and disadvantages of the bridge rectifier circuit, compared to the center-tap circuit With a low-voltage source such as the one you’re using (6 volts RMS), this disadvantage is easily measured. During the negative part of the wave cycle, the circuit produces zero volts. Advantages and Disadvantages of Full Wave Rectifier Over Half Wave Rectifier Advantages. 6. 0 0. A center tap full wave rectifier has only 2 diodes where as a bridge rectifier has 4 diodes. Manufacturing of the center-tapped transformer is quite expensive and so Full wave rectifier with center-tapped transformer is costly. INSTRUCTIONS. It provides better rectification efficiency than a half-wave rectifier. Disadvantages of Full-Wave Rectifier. Transformer utilization factor, in case of a bridge rectifier, is higher than that of a centre-tap rectifier. It is an expensive circuit due to more components. If stepping up or stepping down of AC voltage is not needed, and then it does not even require any transformer. For a full wave rectifier, the maximum possible value of rectification efficiency is 81.2 % while that half wave rectifier is 40.6 %. 40.6%. In half-wave rectifier, only a positive cycle is rectified and the negative cycle is attenuated. It requires four semi conductor diodes 2. I can think about 4 specific merits at this point.
