The paper presents a brief review of the operation of multiphase converters controlled by algorithms of synchronized pulse width modulation (PWM). Basic peculiarities of space-vector-based method of synchronized PWM have been described. Examples of dissemination of this new method are presented for the control of: a) five-phase inverters controlled at both under-modulation and over-modulation ranges; b) six-phase inverters for drive system with symmetrical six-phase induction machine, and c) six-phase inverters for asymmetrical six-phase motor drive. It has been shown, that the proposed PWM method provides continuous output voltage synchronization for any operating conditions of power conversion systems.

Abstract

The paper presents a brief review of the operation of multiphase converters controlled by algorithms of synchronized pulse width modulation (PWM). Basic peculiarities of space-vector-based method of synchronized PWM have been described. Examples of dissemination of this new method are presented for the control of: a) five-phase inverters controlled at both under-modulation and over-modulation ranges; b) six-phase inverters for drive system with symmetrical six-phase induction machine, and c) six-phase inverters for asymmetrical six-phase motor drive. It has been shown, that the proposed PWM method provides continuous output voltage synchronization for any operating conditions of power conversion systems.
