講題簡介：
The matrix converter is an array of power semiconductor switches that connects directly
the three-phase AC source to the three-phase load. It can convert fixed voltage and fixed
frequency AC power to variable voltage and variable frequency AC power directly without
DC link and bulk energy storage component. Classical modulation methods such as maximum
envelop modulation (Venturini method), Space Vector Modulation (SVM), implement matrix
conversion successfully. However, in the mean time they cause very high total harmonic
distortion (THD).
This seminar presents a Sub-Envelope Modulation (SEM) method to reduce THD for
matrix converter. The approach is extended to an improved version of matrix converter and
the THD can be reduced further. The algorithm of SEM is described in detail. The method of
current commutation is also proposed. Simulation and experiment results are also presented to
verify the feasibility of SEM approach. The results will be very helpful to industry
application.
