A typical capacitor input filter consists of a filter capacitor C1, connected across the rectifier output, a Choke L , in series and another filter capacitor connected across the load. # The capacitor C1 offers low reactance to the AC component of the rectifier output while it offers infinite reactance to the DC component. As a result the capacitor bypasses an appreciable amount of the AC component while the DC component continues its journey to the choke L # The Choke L offers high reactance to the AC component but it offers almost zero reactance to the DC component. As a result the DC component flows through the choke while the AC component is blocked. # The capacitor C2 bypasses the AC component which the choke had failed to block. As a result only the DC component appears across the load. |
