Capacitor, Inductor, LC, Pi Filter circuits for DC power supply
A pi filter is a shunt capacitor filter followed by an LC filter which is arranged like the Greek letter π, hence it is called a pi filter. The pi filter gives steadier and smoother DC compared to other filters. The shunt capacitor C1 does the main filtering. The voltage across the C1 can be expected as a similar waveform of the capacitor filter.
