Predictive control of a three-phase neutral-point-clamped inverter
R Vargas, P Cortés, U Ammann… - IEEE Transactions …, 2007 - ieeexplore.ieee.org
A new predictive strategy for current control of a three-phase neutral-point-clamped inverter
is presented. The algorithm is based on a model of the system. From that model, the
behavior of the system is predicted for each possible switching state of the inverter. The state
that minimizes a given quality function is selected to be applied during the next sampling
interval. Several compositions of are proposed, including terms dedicated to achieve
reference tracking, balance in the dc link, and reduction of the switching frequency. In …

A new predictive strategy for current control of a three-phase neutral point clamped inverter
is presented. It is based on a discrete-time model of the system, used to predict future values
of the load current and voltage of the capacitors in the DC-link, for each possible switching
state generated by the inverter. The state that minimizes a given quality function" g" is
selected to be applied during the next sampling interval. Several compositions of g are
proposed, including terms dedicated to achieve reference tracking, balance in the DC-link …
