2009 Fifth International Joint Conference on INC, IMS and IDC
A Class of New AC-DC-AC Matrix Converter ACCMC
Seoul, Korea

This paper proposes a new class of matrix converters (MCs) referred to as AC chopper matrix converters (ACCMCs). They are AC-DC-AC MCs, of which rectifier stages are 3/2 phase MCs, and inverter stages are DC-AC inverters based on AC chop principle. The main attribute of the new MC topologies are the fact that it generates high voltage transfer ratio, depending on the instantaneous duty cycles. This property is not found in the conventional AC-AC MC. The basic configuration of these new topologies and their fundamental principles are introduced. The validity and feasibility are tested by simulation and prototype experiments. The results indicate that the output voltage transfer ratio can exceed 1.0 and the harmonic distortion of output voltage waveform is not high. This study may provide inspiration for further engineering application.
