用可変電圧・可変周波数インバータ制御装置。[Claims for Utility Model Registration] Speed generators attached to four motor shafts, a reverse detection circuit that checks the phase relationship of these output signals to detect when the vehicle is moving backwards, and speed information from the speed generators. A variable voltage/variable frequency inverter consisting of a logic section that calculates information from the main controller and controls the speed of the vehicle, and a gate drive circuit that amplifies the power of the calculation result of the logic section and drives a gate turn-off thyristor. In the control device, a majority logic circuit is added which has the function of checking the backward determination results for the four axes outputted by the backward detecting circuit and giving a backward command to the logic section when the results of three or more of the four axes match. A variable voltage/variable frequency inverter control device for a vehicle, which is characterized by:
