“…The four-level multiphase topology is aimed at the high-power and traction applications where the well-known advantages of multiphase machines and multilevel converters are of particular significance. Open-end winding drives are particularly suited to EVs/HEVs [4] and electric ship propulsion [5], where use of two isolated supplies does not present a problem.…”

AbstractThe paper studies pulse width modulation (PWM) techniques for a five-phase multilevel open-end winding drive with two inverters supplied with unequal dc-link voltages, which are in the ratio 2:1. It is shown in the paper that application of in-phase disposition modulation (PD-PWM), often used in multiphase multilevel converters, results in overcharging of the capacitor in the dc-link of the converter intended to operate at the lower dc voltage. The voltage space vector combinations which lead to the overcharging are identified and two decoupled modulation techniques which do not activate the troublesome vector combinations are proposed. The performance of the developed modulation techniques is investigated using simulations and an experimental prototype, and the results are presented in the paper.

“…This topology is aimed at high-power applications where the well -kno wn advantages of multiphase machines and multilevel converters are of importance. OeW drives are particularly interesting for EVs/ HEVs [5] and electric ship propulsion [6,7], where use of two isolated supplies may not represent a problem. The OeW topologies have also been investigated as a means of extending the operating speed range of five-phase permanent magnet synchronous [8] and three-phase induction machine [9] drives.…”

“…Early works focused generally on fault-tolerant capability [1], [2]. Further investigations have shown other advantages, such as a reduced complexity compared with multi-level inverter drives [3], increased power for the same ratings of switching components compared with the conventional star-connected topology [4], the possibility to integrate a charger functionality without any additional component for electric vehicles [5], [6], a method to boost the supply voltage [7] and a topology for supplying the machine 1 with two isolated sources that can exchange energy between them [8]. Several converter topologies have been suggested to be associated with three-phase open-end winding machines [9].…”
