電流形ソンバータ回路。 A self-extinguishing type inverter circuit for DC brushless motors that detects the position of the rotating field magnetic pole using a magnetic pole position detector and drives the motor while switching the DC current based on this position. An inversion bridge formed by connecting semiconductor switching elements in a three-phase bridge configuration, a small capacitor connected to the input end of this inversion bridge, and an intervening device between the input end of the inversion bridge and a DC power supply. 1. A current source sonverter circuit for a DC brushless motor, characterized in that the conduction period of each semiconductor switching element of the inverse conversion bridge is slightly shorter than 120 degrees in electrical angle.
