| 摘 要： | 分布式供电直流变换器与逆变器级联系统具有很强的时变和非线性特性,级联式DC/DC变换器的稳定性是分布式供电系统中的重要问题。文中重点以DC/DC变换器与DC/AC逆变器连接为例分析逆变器输入滤波对系统稳定性的影响。通过实验验证,在逆变器侧串联LC滤波器,利于系统稳定。

| Abstract: | DC distributed power DC/DC converters and DC/AC inverter cascaded systems have strong time-varying and non-linear property.Stability issues of cascaded DC/DC converters are very important in distributed power systems.Connection between DC/DC converters and DC/AC inverters is modeled to analyze the influence of input filter to stability of the system in detail.It is beneficial to stability of the system to add a LC filter between the converter and the inverter,which has been proved by experiment. |
