What are the advantages of three phase rectifier over a single phase rectifier?

Advantages of three-phase rectifier over a single-phase rectifier:
  • The transformer utilization factor is high.
  • More efficient than a single-phase system.
  • The power output and therefore rectification efficiency are quite high.
  • Ripple factor is too much lower and therefore they high-cost filtering is not required to give steady DC output.
  • The output current in the load contains very little Ac component as compared to a single-phase rectifier.
  • Lower amplitude ripple. so the output voltage is smoother.
  • Size is small compared to the single-phase system.
  • High output voltage for given input voltage.
