A novel power management control strategy for photovoltaic power system is proposed. The solar cell array powers the steady state energy and the battery compensates the dynamic energy in the system. The goal of the power management control strategy is to control the un-directional DC-DC converter and bi-direction DC-DC converter to operate in suitable modes according to the condition of solar cell and battery, so as to coordinate the two sources of solar cell and battery supplying power and ensure the system operates with high efficiency and behaviors with good dynamic performance. A 500W experimental prototype of photovoltaic power system was built in the lab. Experimental results are shown to verify the effectiveness of the proposed power management strategy..
