摘要
提出一种全新低输入纹波单级隔离反激拓扑结构,实现输入电流低纹波,使得电池板更易实现最大功率点跟踪(MPPT),并且能够同时实现逆变器的高转换效率和高可靠性。通过理论分析、计算模拟和实验验证等方面验证了技术的正确性、先进性和可行性,为推动太阳能和风能等清洁能源的广泛应用提供理论指导和技术支持。
A new low-frequency current ripple isolated flyback topology to stabilize the output current and voltage of PV modules with ultra-small capacitor is proposed in this paper. Therefore Maximum Power Point Tracking（MPPT） can be easily done and high conversion efficiency and high reliability can be achieved at the same time. Operation principle of the new topologies is analyzed in details. Based on this innovation idea, theory analysis, modelling, simulation and test will be carried out to demonstrate the advan- tages of this novel topology and its control method. The development of this key technology and the control method will provide technical supports and be very useful for a wide application of solar energy.
