Advantages and disadvantages of π filter

Advantages:

There are some advantages of π filter which are given below.

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

Disadvantages:

There are some disadvantages of π filter which are given below.

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