Abstract
This paper proposes implementation of a carrierbased space vector pulse width modulation (SVPWM) strategy through an analogue method for a three-leg voltage source inverter (VSI) providing both balanced and unbalanced twophase outputs. The phase difference angle of output voltages is kept at 90 degrees whilst the amplitude is adjustable. The mathematical approach to a waveform synthesis is proposed. The circuit design in accordance with mathematical equations of the analogue modulator is given. The correctness of the proposed method is verified by both simulated and experimental results. © 2008 IEEE.
