Predictive current control for a VSI with reduced common mode voltage operating at fixed switching frequency

In this paper a predictive current control strategy with a fixed switching frequency for a voltage source inverter is proposed, with the aim of obtaining a modulated waveform at the output of the converter with a natural reduction of the common mode voltage. The feasibility of this strategy is evaluated using simulation results to demonstrate the advantages of predictive control, such as fast dynamic response and the easy inclusion of nonlinearities and they are compared with the modulated model predictive control (M2PC) proposed recently.
