Abstract

PURPOSE:To improve the power factor of a Scherbuis device in a high speed operation range by controlling one of converters connected to the secondary voltage rectification output terminal of a motor as an inverter when the motor becomes high speed operation and the other as a converter. CONSTITUTION:The secondary voltage of an induction motor 3 is rectified by a rectifier 51, and is fed back to a power source 1 via converters 53, 54 and current transformer 56. The converters 53, 54 are controlled as inverters in a low speed operation range (approx. 1/2 or less of the Scherbius speed controlling range). When the motor operates in high speed operation range (approx. 1/2 of higher of the Scherbius speed controlling range), this state is detected by a speed detector 30. A phase control circuit 53 produces a control signal for operating the converter 53 as a converter. A phase control circuit 54 produces a control signal for generating a 100% inverter voltage by displacing the control leading angle beta of the converter 54 to beta limit.
