摘要

双Boost单相逆变器能够实现单级升压逆变，适用于分布式能源并网发电领域。针对其并网控制策略难以兼顾高性能的动态响应特性以及交直流侧电能质量的问题，在分析双Boost单相逆变器并网工作原理、功率解耦以及谐振机理的基础上，提出了一种由单并网电流环、功率解耦和有源阻尼组成且具有对称结构的并网控制策略，分析并介绍了各部分控制原理。最后，仿真和实验结果表明，所提控制策略具有动态响应速度快、并网电流质量高、直流侧无二次功率脉动等优点。

Abstract

The double Boost single-phase inverter is an inverter with voltage boosting capability in single power stage

which is suitable for grid-connection of distributed energy. The conventional control strategy cannot achieve good performance of grid current tracking and AC/DC power quality at the same time. Based on the analysis of working principle

power decoupling and resonance mechanism of grid-connected Boost inverter

this paper proposes a grid-connected control strategy with symmetric structure. The control strategy is made up of single current control loop

power decoupling control and active damping control. Moreover

the working principle of each part in the proposed strategy is also analyzed in detail. Finally

the simulation and experiment results show that the proposed strategy not only can achieve fast dynamic response and high-quality grid-connected current

but also can significantly mitigate the second order harmonic component in DC current.
