In this paper, a strategy for detecting the instantaneous phase voltage is presented. For the wye connection, all the “negative” terminals of the inverter outputs are tied together, and for the detla connection, the inverter. . The use of pulse width modulated (PWM) inverters is nearly universal in industrial drives, making accurate voltage measurements problematic due to the switching nature of the applied phase voltage. Often, the applied phase voltage is reconstructed by using a combination of the DC link voltage and. . The DC voltage of the vehicle battery is converted by the three-phase pulse width modulated inverter into a three-phase current and switched to a three-phase motor. Unfortunately, a pulse nature of inverters voltages and currents contributes to the problem of a common-mode voltage (CMV), which is the source of many harmful phenomena. . tage or current. The inverter does reverse of what ac-to-dc converter does (refer to ac t dc converters).
