Design on Power System of a Solar Powered Autonomous Underwater Vehicle

The common structure of power system of SAUV is introduced,aiming at solar cell array and solar battery charger,much work is done specially.The system design of solar cell array and solar battery charger is proposed,and the maximum power point tracking(MPPT) is discussed,focusing on variable-step perturb and observe method.Then the charging strategy is described and software flowchart is presented.
