A new PWM regulator to minimize the inverter losses

The losses in electric drives are an important factors to determinate the rating of inverter switches. In this study we develop a new Pulse Width Modulation (PWM) to decrease the inverter losses. This new PWM method gives less inverter commutation losses than classical PWM, especially in high carrier frequency. The new method decrease the volume and price of drive. To simulate the conduction and commutation switches losses in inverter, we have developed a method using datasheet of switches.
