Abstract
A harmonic component extraction unit obtains a command value of compensating current from a harmonic component of the load current. A difference current generation unit obtains a deviation between the compensating current and a value obtained by leading a phase of the command value by a predetermined phase difference. A current controller generates a control signal based on output of the difference current generation unit. A driving signal generation circuit generates, based on the control signal, a driving signal driving a parallel active filter.
