Abstract :
The authors reexamine the issue of modulation strategies and their impact on performance characteristics such as dynamic control, current ripple, and acoustic noise. It is seen that significant performance improvement can be obtained by factors such as choice of reference frame, the use of space vector strategies, and the use of voltage or current regulator inner loops. The use of synchronous frame regulators is seen to yield significant improvement in overall modulator performance. It results in elimination of fundamental component errors and significantly improved DC bus utilization. The results presented have been extensively verified using simulation and laboratory experiments
