Resumen
In this work a study of a 27-level asymmetric
multilevel current source inverter is developed. The presented
structure is composed by three current source inverters that
together are in a 9:3:1 ratio to produce a current waveform with
multiple levels. A model predictive control scheme is developed
for tracking the references for the output AC voltages, and
to keep the asymmetric ratio between the DC currents even
during transient conditions. Furthermore, an extra control goal
is included in order to reduce the commutations of the inverter,
and therefore reduce the power losses. In order to apply the
predictive controller, the equations of the model to be analyzed
are obtained systematically for continuous and discrete time
domains. Simulations are carried out to validate the proposal
and the integrity of the predictive control strategy.
