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.
