Basic Aspects of the Theoretical and Practical Relevance of the Method of Synchronous Multi-Zone PWM for Power Inverters

Abstract

This paper briefly reviews the development and widespread use of an alternative method of synchronous multi-zone pulse width modulation (SMZ PWM), based on a non-standard time-domain-oriented space vector approach, for the adjustment of voltage source inverters (VSINs) and inverter-based ac drives with relatively low switching frequency (SwFr) of VSINs.
