Beschreibung
Zusammenfassung:	In an inverter circuit including switching devices and diodes connected in parallel with the switching devices which are provided in pairs of upper and lower arms, and also including resistances for detecting phase currents in a motor connected to the lower arms, during dead time periods when both a switching device in an upper arm and a switching device in a lower arm are off, a voltage across a phase-current detection resistance induced by a phase current flowing through a diode is sampled.
