2012 IEEE 13th Workshop on Control and Modeling for Power Electronics (COMPEL), 2012
This paper proposes a space vector modulation based on the virtual AC/DC/AC conversion method for a matrix converter to reduce the switching loss. The switching loss of the matrix converter is not decided by only the number of switching times but also depending on the voltage and current in the selected switching devices based on the modulation.

2014 IEEE 15th Workshop on Control and Modeling for Power Electronics (COMPEL), 2014
This paper proposes a modular converter system to achieve high power density, high system bandwidth and scalability for isolated bidirectional DC/AC and AC/DC three-phase power conversion. The approach is based on high frequency isolated series resonant converter (SRC) modules with series output connection and a low frequency three-phase unfolder.

2009 IEEE Electric Ship Technologies Symposium, 2009
The proliferation of large non linear loads such as main propulsion and thruster variable frequency drives (VFDs) on both warships and commercial vessels, high voltage power supplies for lasers and other advanced weapons on warships require both AC voltage transformation and power conversion from AC to DC.

Evaluation of harmonies and interharmonics produced by AC/DC/AC conversion systems
2004A new model of line commutated AC/DC/AC conversion systems is presented and discussed. It is based on the inclusion of the modulation function approach inside the Iterative Harmonic and Interharmonic Analysis algorithm. The new model allows to perform the evaluation of waveform distortion taking into account comprehensive representations of both ...
