Claim 1:
2. The apparatus of claim 1, wherein
the switching elements include a top switch and a bottom switch of one leg of legs of a three-phase inverter,
the Rogowski coil includes a first Rogowski coil and a second Rogowski coil configured to detect switching currents passing through the top switch and the bottom switch, respectively, and to output differentiated values,
the integrator includes a first integrator and a second integrator configured to integrate the differentiated values received from the first and second Rogowski coils, respectively, and
the reset circuit includes a first reset circuit and a second reset circuit configured to respectively apply a reset operation to the first and second integrators for the respective switching periods of the switching elements so that the offset integrated value is not accumulated when the first and second integrators perform integration.
