Abstract

PURPOSE:To detect current with minimum loss thorough a very simple structure, by detecting conduction voltage of MOSFET in a power inverter and outputing the detected value as a motor current value. CONSTITUTION:A drive circuit 3 outputs gate signals to gate terminals 8a-13a of respective MOSFET 8-13 in a power inverter 4 on the basis of a position detection signal SG1 fed from a rotor position detecting circuit 2 and makes ON/OFF control of respective MOSFETs 8-13. A current detection circuit 7 is connected to gate terminals 11a-13a of MOSFETs 11-13 in the power inverter 4 and respective windings IU, IV, IW. Conduction voltage of MOSFET is detected and the detected value is outputed as a motor current value.
