  • Method of feeding asynchronous motors with an inverter, in particular for battery-powered vehicles
    Patent number: 6246208
    Abstract: The present invention relates to a method of feeding asynchronous motors with an inverter, of the type comprising a driver of the inverter and feedback of the voltages at the terminals of the asynchronous motor. The abovementioned method measures the duty cycle of the voltages at the terminals, compares it with reference values, calculating the errors between actual duty cycle and ideal duty cycle, in order to obtain, by means of further application of a PI control algorithm, compensation of the driver, eliminating the distortions introduced by the inverter itself.
