The SCR is capable of conducting OR blocking current in the forward direction, depending upon the gate signal. The SCR, like the diode, will always block current flow in the negative or reverse direction.

Hence SCR operates as a controlled rectifier and hence the name silicon controlled rectifier. The output voltage from the SCR rectifier is not a purely dc voltage but also consists of some ac components, called the ripples, along it.
The ripple components are undesirable and need to be removed or filtered out.
