ル１の間に抵抗器７を挿入する方法である。(Prior Art) In the inverter device that drives the induction motor shown in FIG. 2, in order to obtain a high regenerative braking force, it is necessary to increase the voltage applied to the induction motor in the regeneration mode. In FIG. 2, 1 is a filter reactor, 2 is a filter capacitor, 3 is an inverter section composed of a GTO thyristor, and 4 is an induction motor. Two methods have been put into practical use to make the regenerative voltage generated by the induction motor 4 higher than the power supply voltage. One method is to insert a resistor 6 into each phase of the induction motor 4 and inverter 3 as shown in FIG. This method involves inserting a resistor 7.
