A system and method for optimizing current filtering in a motor soft starter is disclosed. A motor soft starter includes a circuit having an input connectable to an AC source and an output connectable to an input terminal of an AC motor, with the circuit being operable in a ramping mode and a bypass mode so as to control current flow and terminal voltages in the AC motor. The soft starter includes a controller connected to the circuit to control operation thereof, with the controller including a configurable current filter. The controller determines a current of an AC power provided to the input terminal of the AC motor from the soft starter, identifies a present operational mode of the soft starter as being one of the ramping mode and the bypass mode, and performs filtering on the determined current based on the present operational mode of the soft starter.
