Review of Overmodulation Control Techniques of Drive Inverters with Synchronous Space-Vector PWM

Abstract

This manuscript presents short survey of basic techniques and algorithms of synchronous space-vector modulation for control of voltage source inverters of motor drives in the overmodulation control mode. These control regimes are characterized by specific control schemes which are differ from schemes of synchronous PWM for linear (undermodulation) control regimes of inverters. So, specialized overmodulation-focused schemes, techniques, and algorithms of synchronous PWM have been reviewed regarding some basic topologies of drive inverters: a) standard three-phase inverters; b) dual three-phase and six-phase systems; c) modular converters; d) triple-inverter-based systems, and e) five-phase inverters.
