Predictive current control of a new three‐phase voltage source inverter with phase shift compensation

This study presents a finite‐control‐set model predictive current control (FCS‐MPCC) with phase shift compensation for a cost‐effective voltage source inverter. Firstly, the FCS‐MPCC algorithm uses the discrete‐time model of the inverter to predict the coming value of the load current. In addition, a cost function is defined to evaluate all possible voltage vectors from the inverter, where the cost function is selected. Moreover, a pulse computation module is developed to obtain the final switching signals for insulated‐gate bipolar transistors. In addition, the problem of current distortion caused by phase shift is solved by employing a time interval compensation factor. Furthermore, a comparison between the hysteresis control, pulse‐width modulation control, and proposed predictive control is presented in terms of the steady‐state and dynamic performances. Both simulation and experiment are conducted, which confirm the validity of the proposed control scheme of FCS‐MPCC.
