Based on abc Coordinates Space Vector Control of Three-Phase Four-Leg Inverter Power Supply Simulation

Abstract

This paper presents a new space vector control method, based on three-phase abc coordinates of the space vector control method, avoiding the αβγ coordinates of the coordinate transformation, reducing the role of the space vector and its time complexity greatly, More easy-to-digital control implementation. Meanwhile, according to three-phase four-leg circuit average current model, given the instruction voltage vector of the theoretical derivation, abc coordinates based on space vector control method carried out a detailed theoretical explanation. The simulation results illustrate that this method is applicable to different types of load, the output voltage sine have good waveform.
