Based on maximum output current DC/ DC(Direct Current-Direct Current) converter to track the maximum power point of solar panels, fuzzy logic control theory is applied to solar power management circuits for intelligent charge and discharge management. DC/ DC converter mathematical model is established, the theoretical deduction is based on that the maximum output current tracks the maximum power point of solar panels. STM8L151K4T6 single-chip microcomputer is used to control Sepic converter circuit achieving the small power of 3 W solar panels of maximum power point tracking, to control the element battery for constant-current to constant voltage charge control and charge discharge protection, the experimental results validate the correctness and rationality of the design implimenting the optimal control circuits of solar power management.
