Abstract

The linear control of DC Link voltage in PWM inverter is very importent to estimate the goodness of PWM method. In motor control system, for the maximum torque on full region operating, the whole of DC Link voltage region must be used. 3 phase sinusoidal PWM inverter has a low efficienty at the using of output voltage. according to make better the efficiency, new improved PWM control method is proposed. The results of experimentation and simulation are included to verify the validity of this method.
