对于逆变器并联系统,各模块输出电压之间如若存在幅度和相位上的差异,势必会产生在模块间流动的环流。文中在逆变器并联系统环流产生机理分析的基础上,对是否加入环流反馈时系统的阻抗和稳定性进行了分析,证明采用环流反馈可以增大系统环流阻抗,在保持输出电压不变的前提下有效地减小了环流,最后通过Simulink仿真证明此方式的有效性。

For parallel inverter systems, the amplitude and phase differences among the output voltage of each module are bound to generate the circle current among modules. Based on the mechanism analysis of inverter parallel system circle current, this paper analyzed that whether to join the impedance and stability of circle current feedback system, which showed that the circle current feedback can be used to increase the circle current impedance, and keeping the output voltage constant can bring on the decrease of the circle current. Finally, the effectiveness of this approach is proved by Simulink simulation.
