Comparative Analysis Between Axial and Coaxial Magnetic Couplings
Presentation / Conference Contribution
Akcay, Y., Giangrande, P., Gerada, C., & Galea, M. (2021). Comparative Analysis Between Axial and Coaxial Magnetic Couplings. In The 10th International Conference on Power Electronics, Machines and Drives (PEMD 2020). https://doi.org/10.1049/icp.2021.1147

The adoption of magnetic couplings enables the transmission of mechanical power relying on the magnetic fields interaction rather than a physical mechanical connection. Hence, the contactless speed/torque transmission leads to improvements in terms o... Read More about Comparative Analysis Between Axial and Coaxial Magnetic Couplings.

A new class of hybrid AC/AC direct power converters
Presentation / Conference Contribution
Klumpner, C., Wijekoon, T., & Wheeler, P. A new class of hybrid AC/AC direct power converters. Presented at 2005 IEEE Industry Applications Society Annual Meeting

Variable voltage and variable frequency conversion of electrical energy from an AC source to an AC load is done in traditional power converters via a DC-link where an energy storage element (electrolytic capacitors) is situated. Despite its well-know... Read More about A new class of hybrid AC/AC direct power converters.

A hybrid indirect matrix converter immune to unbalanced voltage supply, with reduced switching losses and improved voltage transfer ratio
Presentation / Conference Contribution
Klumpner, C. A hybrid indirect matrix converter immune to unbalanced voltage supply, with reduced switching losses and improved voltage transfer ratio. Presented at 2006 IEEE Applied Power Electronics Conference and Exposition (APEC 2006)

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...
