| Abstract |
This work presents the design of robust sliding mode controllers for three-phase ac-ac matrix converters,
in order to guarantee output sinusoidal waveforms and leading or lagging input power factor.
Matrix converters may be useful in several applications, such as ac drives. In fact, this is the best known
application for matrix converters, which, in this case, operate mostly with unity input power factor.
However, for other applications, such as static VAR compensators (SVC) or phase shifters a fully
controllable input power factor is useful.
A control method is proposed which ensures that the output voltage and input current track their
references, guaranteeing the desired power factor.
The obtained results show that sliding mode controllers guarantee an on-line control of the matrix
converter output voltages, with leading or lagging input power factor. |
