This paper gives a new type of solar power charging circuit topology program in order to improve the utilization of solar energy and improve photovohaic power generation system capability. The program involves the use of a conduction module to connect solar panels and rechargeable batteries in the program and the adoption of dynamic voltage regulator to realize the conventional charge and voltage doubling charge of battery as a solution to the solar battery energy outflow question. The experiment prototype show that the module exhibits a better consummation charge control and low-voltage charge, quiescent current of less than 20μA, and transmission efficiency up to 98% , and so it is capable of operating as a practical and efficient charge control module.
