Multiphase systems are nowadays considered for various industrial applications. Numerous PWM schemes for multiphase voltage source inverters with sinusoidal outputs have been developed, but just recently the impact of these modulation schemes on the output peak-to-peak current ripple amplitude has been considered. Determination of current ripple in multiphase PWM voltage source inverters is important...
<para> A multilevel inverter topology feeding a three-phase open-end winding machine is analyzed in this paper. The scheme is based on the use of two insulated dc supplies, each one feeding a standard two-level three-phase inverter. The three-phase six-wire winding is connected across the output terminals of the two inverters. A new modulation technique that is able to regulate the sharing of...
A multilevel inverter topology feeding three-phase open-end winding loads is considered in this paper. The scheme is based on two insulated dc supplies, each one feeding a standard two-level, three-phase inverter. A three-phase six-wire load is connected across the output terminals of the two inverters. A new modulation technique able to regulate the sharing of the output power between the two dc...
