摘要

本文首先利用混沌空间矢量脉宽调制(SVPWM)控制来改善光伏逆变器的电磁干扰特性。根据混沌SVPWM控制的工作原理，它具有成本低、设计简单、不需要EMI滤波器就能抑制EMI的优点，给出了混沌SVPWM控制的实现方法。此外，混沌SVPWM还用于改善光伏逆变器的总谐波失真(THD)，其中混沌载波在实现混沌SVPWM控制中起着关键作用。最后，给出了不同输出电感的光伏逆变器的仿真结果，验证了混沌SVPWM在抑制电磁干扰和改善THD方面的有效性。

Chaotic SVPWM control and its application in EMI suppression for PV inverters

This paper firstly use the chaotic space vector pulse width modulation (SVPWM) control to improve the EMI characteristic of photovoltaic (PV) inverters. According to the operating principle of chaotic SVPWM control, it has the advantages in low costs, simple design and suppressing EMI without EMI filter, the implementation method of the chaotic SVPWM control is following provided. Furthermore, the chaotic SVPWM is also employed to improve the total harmonic distortions (THD) of PV inverters, where, a chaotic carrier plays a key part in implementing the chaotic SVPWM control. Finally, simulation results of a PV inverter with different output inductance are given to validate the effectiveness of the chaotic SVPWM in suppressing EMI and improving THD.
