摘要
针对传统桥式逆变电路的桥臂直通问题,设计了一种基于模型预测控制的双降压式全桥并网逆变器,该电路结构无需输入均压大电容,输入电压利用率高、开关器件电压应力低,所采用的模型预测控制具有无需调制器,算法简单,可处理多变量、多种非线性约束的优点.通过一台额定功率1k W的实验样机验证,实现了逆变器的高效率、高可靠性设计,表明了设计方法的可行性.
A dual-buck full-bridge grid-connected inverter based on model predictive control is designed to solve the bridge-through problem of the traditional bridge inverter. The input voltage equalizing capacitor is not necessary for this circuit. This inverter has a high input voltage utilization rate and low voltage stress of the switching device. In addition, the applied model predictive control has the advantages of no modulator, simple algorithm, and the ability of handling multiple variables and multiple nonlinear constraints. A prototype with a rated power of 1 kW has been built to verify the high-efficiency and high-reliability design of the inverter. The experiment results show the feasibility of the design method.
