摘要
提出了Z源单相并网逆变器的控制方法;分析了Z源网络和并网逆变器的建模,并在此基础上设计了Z源单相并网逆变器调节器。Z源单相并网逆变器控制系统由Z源网络电容电压控制环和输出并网电流控制环组成。Z源网络电容电压控制环采用PID调节;输出并网电流控制环采用PI调节。仿真和实验都验证了Z源单相并网逆变器控制方法的正确性和可行性。
A control method of Z-source inverter as a single phase grid-connected power conditioner is presented.After modeling the Z-source network and inverter system, modulators for the two close loops of Z-source inverter as a single phase grid-connected power conditioner are designed in a control system mode.The modulator of the Z-source network is realized by proportion integral differential （PID） element.Finally,the simulation and experimental results verify the validity of the proposed control method.
