Simplified Space Vector Pulse with Modulation Algorithm for Three Level Inverter with Neutral Point Potential Control

摘要

In this study, we present an algorithm for the Space Vector Pulse with Modulation (SVPWM) applied to three level diode clamping inverter. In this algorithm, the space vector diagram of the three level inverter is thought that is composed of six space vector diagrams of two level inverters. This idea allow us to generalize the two level SVPWM algorithm into the study of three level inverter. The redundant vectors of the space vector diagram of three level inverter are used to asserve the neutral point potential of the inverter.
