Improved model predictive current control of a dual buck full-bridge inverter

According to the characteristics of dual buck full-bridge inverter, an improved model predictive current control (MPCC) strategy is used. Compared with the traditional model predictive current control scheme, the new model predictive current control can reasonably allocate times of different switching state through the principle of the minimum current error in a single sampling period, which can reduce the inductor current ripple caused by dual buck full-bridge inverter and improve output waveform quality of the dual buck full-bridge inverter. Simulation and experimental results verify the feasibility and correctness of this scheme.
