It can be used in research and development of solar cell power generation technology applied in the test when used. The developed solar cell simulator is an interleaved buck-boost power converter controlled by a DSP chip. It is similar to the actual solar cell output-current and output-voltage characteristics. To verify the performance of the developed solar cell simulator, computer simulation is carried out and hardware prototypes is developed and tested. Both simulation and experimental results verify that the solar cell simulator has the electrical characteristics of the actual solar cell. This paper presents a fast charging strategy for a solar power system. By using the maximum power point tracking and pulse charging technologies, the solar charger will operate in four charging operated modes depend on the variable output power of solar generators. Finally, the proposed charging method developed in this paper is compared with the traditional charging method to verify the feasibility. The experimental results show that the performance of proposed charging strategy is as expected.
