| 摘 要： | 传统MPPT电路串联在光伏组件和负载之间.光伏板产生的所有电能都要经过DC/DC变换器进行处理.因此.整个光伏发电系统的效率就要依赖于DC/DC变换器的效率.针对离网型光伏发电系统提出一种两象限DC/DC变换电路,并将最大功率跟踪电路与其并联,主要能完成蓄电池充放电,升降压电路的功能.由于与主电路并联,仅有少部分能量通...

| Abstract: | The traditional maximum power point tracking(MPPT) circuit series in solar panels and the load.All the power generated by the PV has to pass the DC/DC converter,so the whole process of photovoltaic energy system effi-ciency depends on the efficiency of DC/DC converter.This paper presents a two quadrant DC/DC power converter for stand-alone photovoltaic power generation,and a parallel connected MPPT system is also introduced.It presents the functions of battery charger and step-up converter.The parallel conn... |
