英文摘要：

This paper discusses the control method of DC/DC converter used in PV generation system with energy storage components, and legitimately achieves the control of PV power according to the status of battery and the load. For the application of PV DC/DC, the paper analyzes the power flow of stand-alone PV system, proposes limited power point tracking（LPPT） control method and analyzes the LPPT process under both static and dynamic conditions.It also combine LPPT and maximum power point tracking（MPPT） in order to control the output power of PV flexibly,suits the status of battery and meets the demand of load.The control method is verified on an experimental platform preliminarily.
