A Unified Space Vector Pulse Width Modulation for Dual Two-level Inverter System

Abstract

This Letter proposes a unified space vector pulse width modulation (SVPWM) for adual two-level inverter framework with two confined DC voltage sources. The door pluses for the dual inverter are created by the idea of one unified SVPWM as per the voltage-second vital standard and the ratio of the two DC-interface voltages can be an arbitrary positive value. This proposed strategy additionally improves the district distinguishing proof in areas and decreases add up to exchanging recurrence of the dual inverter. The advantageous execution of this proposed strategy is confirmed tentatively.
