反激型光伏微型逆变器不同工作模式的分析与比较

反激型光伏并网微型逆变器工作模式有不连续导通模式（DCM）和连续导通模式（CCM）两种。在工作原理的基础上,文中通过对这两种工作模式的分析和研究,推导了两种模式下逆变器主要参数的计算公式,从不同方面对两种模式的优缺点进行了对比分析,并得出相应结论,为根据设计要求合理选择逆变器的工作模式提供了理论依据。

The Analysis and Comparison in Different Mode of Flyback Microinverter for PV Module

There are the discontinuous conduction mode(DCM) and the continuous conduction mode(CCM) in flyback microinverter for PV module.Based on the working principle of flyback microinverter,this paper derives the formulas for the main parameter under DCM and CCM through analyzing the condition of two modes,analyzes the advantages and disadvantages of DCM and CCM from different aspects and gives some interrelated conclusions to provide theoretical basis for selecting operating mode according to the design requirements.
