Novel Cuk circuit and Its application in photovoltaic system

This paper designs a isolated resonance Cuk circuit based on the theoretical analysis of Cuk circuit, and do experiment of this circuit, also research the circuit's working principle and transmission efficiency under different load; Combining with the PV arrays working characteristics, this circuit was applied in photovoltaic(PV) generating control system to realize the maximum power point tracking of PV arrays and reduce the electromagnetic interference to external environment. The experimental results show that this novel isolated Cuk circuit has higher transmission efficiency, and can realize the control of the PV cells better.
