摘要
基于光伏并网逆变器的基本原理和控制策略,设计了并网型逆变器的结构,其采用了内置高频变压器的前后两级结构,即前级DC/DC高频升压,后级DC/AC工频逆变。该设计模式具有电路简单、性能稳定、转换效率高等优点。
Based on the basic principle and control strategy of grid connected photovoltaic inverter, the structure of grid connected photovoltaic is designed, which used built-in high frequency transformer with before and after the two-stage structure, namely the former DC/I）C high voltage frequency boost, after stage DC/AC frequency inverter. This design model has the advantages of simple circuit, stable performance, high conversion efficiency etc.
