A complex vector model for three-phase SVPWM voltage-source converter is presented in this paper. It has been proved more convenient to compare the performance of different current controller topologies in the synchronous rotating frame by means of complex vector root locus and complex vector frequency-response functions. An improved synchronous rotating PI current controller is proposed, whose validity and feasibility is verified by detailed simulation and experimental results.
