The capacitance filter circuit's output internal resistance is very big. When the RL changing, the port voltage would also change. Also, the when current-limiting diode is conducted, the impact current is very large which would effect its life. The resistance is small but its AC impedance is very large, that is the inductance filter circuit. So it could use the inductance coil for DC voltage, which is the inductance filter. The picture shows some inductance filter circuit.
The picture shows the inductance filter circuit.
The picture (a) shows the single inductance filter circuit. Its weakness is: generally its filter coefficient (the filter coefficient is the first harmonic voltage amplitude ratio between the filter circuit input port and output port) could only be made under several dozens.
