The commercial power is selected as the back-up energy and a hybrid power system composed of photo- voltaic and commercial power is proposed. The system is composed of a solar cell, the commercial power, a DC-DC converter, a power factor correction converter (PFC) and DC load. The power management is presented for the hy- brid power system to utilize the solar energy. The core of the power management strategy is to keep the system work under suitable mode to control the power flow of the system, according to the work status of the solar cells and the load. The experimental results have confirmed the effectiveness of the power management strategy.
