摘要
针对单相非隔离型光伏并网逆变器进行研究,搭建了Boost+6管H桥的硬件实验平台,并完成了以TMS320LF2407A+TMS320LF2801双CPU为核心的全数字控制算法设计。文中深入分析了6管H桥拓扑对系统漏电流的抑制原理,以及系统的硬件拓扑、控制架构与并网控制策略,并进行实验研究,实验结果证明了该设计方案的可行与实验样机性能的优良。
This research focuses on the single-phase non-isolated PV grid-connected inverter.A prototype with H6-Type bridge and Boost converter is set up.The digital control algorithm is implemented based on two CPUs which are TMS320LF2407A and TMS320LF2801 .The principle of system leakage current suppression with H6-Type inverter is thoroughly analyzed.In addition,the system hardware and grid-connected control strategy are introduced.The experiment results verify that the proposed design scheme is effective.
