Abstract

PURPOSE:To enable the operation improved in the power factor and efficiency by providing a parallel circuit of a current limiting resistor and a contactor normally shortcircuited with the resistor at the normal time in a DC intermediate circuit at the secondary side of a motor, and starting it while controlling the leading angle of the power inverter. CONSTITUTION:A power rectifier 6, a smoothing reactor 7, a parallel circuit of a current limiting resistor 10 with a contactor 3 normally shortcircuited, a power inverter 8 an a power inverting transformer 9 are provided at the secondary side of a wound-rotor type induction motor 1. At the starting time, the controlling leading angle gamma of the inverter 8 is disposed at the minimum position of the operating state, and the contactor 3 is opened. A switch 1 is closed with a start command in this state. Then, the leading angle gamma of the power inverter 8 is controlled to be shifted to the normal state. After it is shifted to the normal state, te contactor 3 is closed.
