Advantages and disadvantages of π type filter

There are some advantages of π type filter which are given below,

  • The quality of output DC voltage is very good.
  • It has higher DC output voltage at heavy loads.
  • It is easy to design.
  • It has very low and smallest amount of ripple factor.
  • It is easy to design.
  • It is useful for low load current i.e. light loads.

There are some disadvantages of π type filter which are given below,

  • It needs larger value of input capacitor.
  • It requires higher PIV (peak inverse voltage).
  • There is a loss of power in inductor.
  • Due to use of more filters, it is costlier and bulky.
  • It has increased peak diode current.
  • It loads the rectifier in case of input capacitor is leaky.
  • It needs the choke of higher current rating.
  • There is a loss of power in the inductor.
