Advantages and applications of polyphase rectifiers

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

• It 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 PIV (peak inverse voltage).
• The polyphase rectifier provides highest TUF (transformer utilization factor).

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

• The polyphase rectifier is used in radio transmitters.
• It is used in electro chemical processing such as production of AI and mg.
• It is used in telephone exchange.
• It is used in electronic heaters.
• It is used in electric traction.
