摘要
研究了2 kW多级光伏逆变器,前级使用推挽电路升压,同时采用F28027实现最大功率点跟踪,后级采用EG8010实现逆变。采用高频链结构,减小变压器、滤波器体积,从而降低装置成本。试验验证了多级光伏逆变器的实用性。
A 2 kW multi-stage photovohaic inverter power supply was researched. Push-pull was used for the first stage to gain voltage, which uses F＇28027 to achieve maximum power point tracking（MPPT）. The second stage uses EG8010 to achieve inversion. High-frequency link was used to reduce the volumes of the transformer and filter and to lower the cost. The correctness of the analysis was verified by experiment.
