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.
