   A FULLY INTEGRATED 30KW MOTOR DRIVE USING MATRIX CONVERTER TECHNOLOGY
By CLARE Jon; DES Lampard; EMPRINGHAM Lee; PICKERING Stephen; WHEELER Patrick; APAP Maurice; KEITH Bradley [View]
[Download]

Abstract: This paper explores the viability of using direct power converter technology to realize integrated motor drives, at power levels significantly higher than is possible with traditional approaches, fitting within the same space envelope as an equivalent motor. The integrated motor design was targeted at pump and fan applications where the need to install motor drives in a separate location is often an impediment to the replacement of fixed speed motors. In order to achieve this objective the thermal and electrical design of the integrated drive have to be considered together. This paper presents the final design that achieves all these objectives, including fully tested and evaluated demonstrations of the power converter and the cooling arrangements. The final integrated motor drive design only differs from a standard motor in terms of one end plate, the terminal box and the shaft driven fan. Full practical results of the 30kW demonstrator are presented in the paper.

   Filtering Techniques for Matrix Converter to Achieve Environmentally Harmonious Drives
By YAMADA Kenji [View]

Abstract: Matrix converter inherently exhibits sinusoidal input current waveforms and has less stressful output voltage waveforms. This paper proposes to integrate the matrix converter with filters that provide lower EMI, lower common-mode current, and lower shaft voltage. These features in combination with the inherently low current harmonic at the input of the matrix converter help achieve drive systems that cause less pollution of the surrounding electromagnetic environment.

   Sensorless Control of PMSMs for deep-sea ROVs excited by Matrix Converters
By BINGHAM Chris; STONE Dave; SNARY Paul; BHANGU Bikramjit [View]
[Download]

Abstract: The paper reports the development of model-based sensorless control methodologies for driving PMSMs using matrix converters. In particular, experimental results show that observer-based state-estimation techniques normally employed for sensorless control of PMSMs using Voltage Source Inverters (VSIs), can be readily exported to matrix converter counterparts with minimal additional computational overhead. Furthermore, zero speed start-up and speed reversal are experimentally demonstrated. Finally, the observer is designed to be fault tolerant such that upon detection of a broken terminal (phase fault), the PMSM remains operational and could be utilized to provide a limp-home capability.
