摘要
正弦载波PWM虽然作为常见的调制策略之一,但并没有相关文献对其仿真模型进行清晰表述。本文针对Z源逆变器的控制特点,依据正弦载波PWM技术原理,运用Matlab软件Simulink工具箱中模块对其搭建仿真模型,并将其应用于Z源逆变器电路。运行仿真后得出相关电压波形,将仿真结果与相关公式计算所得理论值进行比较,从而验证了本文所提供正弦载波PWM仿真模型及其算法的正确性,为相关同行提供使用之便。
Although sinusoidal carrier PWM is one of the common modulation strategies, there is no relevant literature to express its simulation model clearly. According to the control characteristics of Z source inverter, this paper builds a simulation model based on the principle of sinusoidal carrier PWM technology, uses the module of Simulink toolbox of Matlab software to build a simulation model, and applies it to the Z source inverter circuit. After running the simulation, the related voltage waveform is obtained, and the simulation results are compared with the theoretical values obtained from the related formula, and naturally it verifies the correctness of the sinusoidal carrier PWM simulation model and its algorithm provided in this paper, so as to provide convenience for the related peers.
