ABSTRACT:
This paper presents a new inverter based on three-phase
Boost/Buck-boost single-stage inverter. The basic configuration of the new
topology and their fundamental principle are firstly introduced, the method of
design double-loop controller and sliding mode controller are clarified,
analyzed and compared in the following. Finally the validity and feasibility of
the new topology are tested by simulation. The results indicate that regulation
of the voltage transfer ratio and output frequency can be realized optionally
by the new converter, furthermore the harmonic distortion of waveform is low.
So the inherent drawback of low voltage transfer ratio of traditional converter
is effectively settled. This study may provide inspiration for further
engineering application.
