摘要
基于两电平情况下,分析SVPWM与载波PWM之间的相互关系,得出SVPWM的基于载波PWM的统一实现方法,给出算法流程图并进行仿真。最后通过基于DSP(TMS320F28234)的逆变电路分别进行开环逆变实验和有源逆变闭环实验。结果证明了该等效方法在逆变系统中的应用是切实可行的。
On the basis of two-level, this paper analyzed the linkage between SVPWM and PWM of carrier, obtaining the SVPWM unified method base on PWM of carrier and giving the flowchart of algorithm to carry out simulation. Finally, by the inverter circuit based on DSP （TMS320F28234） the open-loop experiments, as well as, the active inverter closed-loop experiments were performed. The results show that the application of the equivalent method is practicable in the inverter system.
