State the advantages of a bridge rectifier.
Answers
1) The rectification efficiency of full-wave rectifier is double of that of a half-wave rectifier.
2) Higher output voltage, higher output power and higher Transformer Utilization Factor in case of full-wave rectifier.
3) The ripple voltage is low and of higher frequency in case of full-wave rectifier so simple filtering circuit is required
4) No center tap is required in the transformer secondary so in case of a bridge rectifier the transformer required is simpler. If stepping up or stepping down of voltage is not required, transformer can be eliminated even.
5) For a given power output, power transformer of smaller size can be used in case of the bridge rectifier because current in both primary and secondary windings of the supply transformer flow for the entire ac cycle
