【Abstract】 The article points out that an output Voltage wave with small high-order harmonic compoents can be obtained by means of controlling thyristors with programmable and erasable memory, to realize frequency modulated velocity regulation of electric cars. With independent frequency control and voltage control the load characteristics of the car can be realized by the load controllers. All these are energy saving measures. Experiments have confirmed the effectiveness of the scheme suggested.更多还原
