摘要
基于逆变器在工程实践中能够实现模块化并且方便操作的目的,采用了9个电源的逆变器闭环系统,通过MATLAB软件中的simulink仿真实验与二分法,实现了较低谐波的交流输出,最后得出这样的结论:传统多电平逆变器结构复杂,控制比较繁琐,容易牵一发而动全身。而新型五电平逆变器则实现了电路的模块化,更加适合在实践中的使用,但对电源耐电流冲击性能要求较高且所需数量较多,对受控源的控制基于实验与二分法,尚待改进。
In engineering practice based on inverter to realize modularization and convenient operation,the purpose of the nine power inverter closed loop system,through the simulink of MATLAB software simulation experiment and dichotomy,implements the lower harmonic of ac output,finally reached the conclusion that traditional multilevel inverter structure is complex,control more complicated,easy to social phenomena. However,the new five-level inverter has realized the modularization of the circuit,which is more suitable for practical use. However,it has higher requirements on the current impact resistance of the power supply and requires more quantities. The control of the controlled source is based on experiment and dichotomy,which still needs to be improved.
