Abstract
A model predictive control strategy for a highpower,
grid connected 3-level neutral clamped point converter
is presented. Power losses constraints set a limit on commutation
losses so reduced switching frequency is required, thus producing
low frequency current harmonics. To reduce these harmonics an
LCL filter is used. The proposed control strategy allows control
of the active and reactive power fed into the grid, reduce the
switching frequency within acceptable operational margins and
keep balance of the DC-link capacitor voltages while avoiding
excitation of the filter resonance frequencies.
