Dissertation
Research on the Uncontrolled Zero-Sequence Current of an Open-End Winding PMSM With Common DC Link
2020
Overview
This thesis describes the research based on a particular type of the motor drives called an open-end winding permanent magnet synchronous motor drive with common DC link. These types of drives are an arrangement of two three phase inverters connected to both ends of a permanent magnet synchronous motor and are fed from a single direct current source. Therefore, it has a return path between the two inverters. This allows the most prominent third harmonic back EMF to introduce the zero-sequence current. Hence, these kinds of motor drives suffer from the circulating zerosequence current. Although this current usually is undesired and, therefore, suppressed using various control techniques, there are some cases when the suppression of this current is unfeasible. Hence, the zero-sequence current could be left flowing in the system. High-speed drives could be considered to be an example of such a system.The research introduced in this thesis is centred on the analysis of the mentioned zero-sequence current that is flowing in the system due to the specific properties of the machine. It features a full mathematical derivation of the nature of the zero-sequence current flowing in the system because of the machine side of the drive and a comprehensive analysis of the power loss in conductor due to this zero-sequence component.The analysis performed in this thesis resulted in a proposal of a couple of novel solutions for the mitigation of the zero-sequence component’s impact on the drive such as the torque ripple and the power loss in conductor. In addition, one of the research outcomes was the development of a novel technique that turns the disadvantage of having the zero-sequence component flowing freely in the drive to its advantage.In addition, the research produced in this thesis led to the development of a software solution that is meant to aid design and control engineers to mitigate the power losses in an open-end winding permanent magnet synchronous motor drive with common DC link.
