摘要

本文介绍了一种新型的单级、单相、共地、无变压器的光伏逆变器。逆变器的理想增益是负无穷到正无穷。变换器是由Ćuk变换器和沃特金斯-约翰逊变换器的智能电路连接而来。输出传递函数的控制包含右半平面(RHP)零，导致闭环带宽有限。目前的程序控制器克服了这一限制。给出了分析基础和仿真结果。

A novel single stage, transformerless PV inverter

This paper presents a novel single stage, single phase, common ground, transformer-less inverter for PV application. The ideal gain of the inverter is minus infinity to plus infinity. Converter is derived from intelligent circuit connections of Ćuk converter and Watkins-Johnson converter. The control to output transfer function contains right half plane (RHP) zeros, which leads to a limited closed loop bandwidth. This limitation is overcame by current programmed controller. Analytical foundations are followed by simulation results.
