摘要

针对双降压全桥逆变器的特点，提出了一种改进的模型预测电流控制策略。与传统的模型预测电流控制方案相比，新型模型预测电流控制通过单采样周期电流误差最小的原理，合理分配不同开关状态的次数，减少了双降压全桥逆变器产生的电感电流纹波，提高了双降压全桥逆变器的输出波形质量。仿真和实验结果验证了该方案的可行性和正确性。

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.
