This paper presents a novel matrix converter
which has high voltage transfer ratio. According to the
topology of the inverter side is different, they are called Boost
matrix converter (BMC) and Buck-Boost matrix converter
(BBMC).The basic configuration of the new topology and their
fundamental principle are firstly introduced, the method of
design sliding mode controller and double-loop controller are
clarified, analyzed and compared. Finally the validity and
feasibility of the new topology are tested by simulation. The
results indicate that the 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 matrix converter is effectively settled. This study
may provide inspiration for further engineering application (2016-01-16, Windows_Unix, 235KB, 下载11次)

A novel Z-source two-stage matrix converter
(ZSTSMC) and its modulation strategy were proposed to
overcome two main drawbacks of conventional matrix
converters, i.e., low voltage transfer ratio and low immunity to
abnormal input voltages. The Boost voltage characteristics of
Z-source network was introduced to improve the voltage
transfer ratio. The shoot-through index was adaptively
controlled by Z-source capacitor voltage closed-loop, so as to
be immune to the disturbance of abnormal input voltages. The
nonlinear PID controller was employed to eliminate effects
caused by non-minimum-phase characteristic presented in
Z-source network and to improve the dynamic performance
and robustness of the system. Finally, the validity and
feasibility of this topology were verified by simulation and
experiment results. (2016-01-16, Windows_Unix, 882KB, 下载7次)
