What are the advantages and applications of polyphase rectifier?

Advantages:

There are some advantages of polyphase rectifiers which are given below,

• The polyphase rectifier provides highest transformer utilization factor (TUF).
• The polyphase rectifiers has a large amount of power, usually greater than 2 kW.
• Its efficiency is greater than as compared to single phase rectifier.
• The ripple factor is reduced in case of polyphase rectifier.
• It facilitates higher peak inverse voltage (PIV).

Applications:
