More electric aircraft starter-generator system with utilization of hybrid modulated model predictive control
Conference Proceeding
Yoeh, S. S., Yang, T., Tarisciotti, L., Hill, C. I., & Bozhko, S. (in press). More electric aircraft starter-generator system with utilization of hybrid modulated model predictive control

The current trend for future aircraft is the adoption of the More Electric Aircraft (MEA) concept. The electrical based starter-generator (S/G) system is one of the core ideas from the MEA concept. The PI based control scheme has been investigated in... Read More about More electric aircraft starter-generator system with utilization of hybrid modulated model predictive control.

A new three-level sparse indirect matrix converter
Conference Proceeding
Klumpner, C., Lee, M. Y., & Wheeler, P. (in press). A new three-level sparse indirect matrix converter. In IECON 2006 - 32nd Annual Conference on IEEE Industrial Electronicsdoi:10.1109/IECON.2006.347958

Matrix converters are forced commutated single stage AC/AC direct frequency changers able to achieve sine wave in and out operation by being able to connect any input phase to any output phase via a 3x3 matrix of bi-directional switches. Indirect two... Read More about A new three-level sparse indirect matrix converter.

Reliable integration of a high performance multi-chip half-bridge SiC power module
Conference Proceeding
Mouawad, B., Li, J., Castellazzi, A., & Johnson, C. M. (in press). Reliable integration of a high performance multi-chip half-bridge SiC power module

Silicon carbide (SiC) devices have been adopted to push the boundaries further in terms of power density, conversion efficiency, switching speed or thermal capability. To have the benefit of such semiconductors, new packaging should be developed to m... Read More about Reliable integration of a high performance multi-chip half-bridge SiC power module.

A hybrid indirect matrix converter immune to unbalanced voltage supply, with reduced switching losses and improved voltage transfer ratio
Conference Proceeding
Klumpner, C. (in press). A hybrid indirect matrix converter immune to unbalanced voltage supply, with reduced switching losses and improved voltage transfer ratio. In Twenty-First Annual IEEE Applied Power Electronics Conference and Exposition, 2006. APEC '06doi:10.1109/APEC.2006.1620528

Achieving a compact and efficient design of power electronic converters is not a straightforward procedure: minimizing the size of the filter requires a higher switching frequency that causes additional switching losses that will require a larger hea...

A new hybrid cycloconverter with smooth output voltage generation capability and accurate control of the circulating current
Conference Proceeding
Klumpner, C., Xu, T., & Clare, J. (in press). A new hybrid cycloconverter with smooth output voltage generation capability and accurate control of the circulating current. In IECON 2006 - 32nd Annual Conference on IEEE Industrial Electronicsdoi:10.1109/IECON.2006.347850

Nowadays, power electronic converters based exclusively on IGBTs deliver excellent load side performance up to megawatt powers in the low voltage range (200-690V) and are steadily gaining performance in the medium voltage range as well. However, the... Read More about A new hybrid cycloconverter with smooth output voltage generation capability and accurate control of the circulating current.
