A four-level five-phase open-end winding (OeW) drive topology is introduced in the paper. The drive comprises a five-phase induction machine with open-end stator windings, supplied using two two-level voltage source inverters with isolated and unequal dc-link voltages, in the ratio 2:1. The topology offers the advantages of a modular structure with fewer semiconductor components and has a greater potential for fault tolerance, compared to an equivalent single-sided fourlevel drive. Due to the large number of switching states, development of a suitable space-vector pulse-width modulation (SVPWM) method can be challenging. Hence, this paper examines the implementation of two level-shifted carrier-based modulation (CBPWM) methods. The effect of dead time on the drive performance is discussed and it is shown that simultaneous PWM switching of both inverters can lead to degraded output phase voltage waveforms. Detailed analysis of this phenomenon is presented, a solution is proposed, and the modified modulation techniques are incorporated in an experimental set-up, at first in conjunction with V/f control. Once when the proof-of-concept has been provided, full field oriented control (FOC) is implemented in this OeW drive topology for the first time; detailed experimental testing is conducted and results are reported. |
