摘　　要：随着传统能源的衰竭,人们开始研究新的能源,如风力发电、太阳能发电等。能否将零散的电源灵活、高效的运用,逆变器发挥着重要的作用。本设计采用MATLAB/SIMULINK2015为平台,以电流滞环跟踪PWM(CHBPWM)为控制单元搭建了一种单相全桥逆变器仿真系统。整套系统主要由主电路、控制电路和采样电路三部分组成。在调制方法的选择上利用了双极性调制的方式。系统给定电流为逆变器的参考电流,反馈电流为逆变器输出电流,实现了闭环控制。设计的滞环控制逆变器输出电流能跟随参考电流变化,输出交流电流正弦度好,总谐波失真率较小,仿真结果与理论分析的数据基本吻合,说明了实际的可操作性。With the exhaustion of traditional energy sources,people began to study new energy sources,such as wind power generation,solar power generation and so on.Inverter can play an important role in the flexible and efficient use of scattered power.In this design,a single-phase full bridge inverter simulation system is built with MATLAB/SIMULINK2015 as the platform and the current hysteresis tracking PWM(CHBPWM)as the control unit.The whole system consists of three parts:the main circuit,the control circuit and the sampling circuit.Bipolar modulation is used in the selection of modulation methods.The given current of the system is the reference current output from the inverter system,and the feedback current is the output current of the inverter,and the closed-loop control is realized.The output current of the inverter system can follow the change of the reference current,the sinusoidal output of the AC current is fine and the total harmonic distortion rate is small.The simulation results agree with the theoretical analysis,which shows the operability in the reality.
