Evaluation on tracking capability of MPPT for running solarcar

Maximum Power Point Tracker (MPPT) is studied to obtain maximum output of PV anytime. There are plural control methods (e.g. Hill Climbing, Genetic Algorithm, Fibonacci Search Algorithm et al.) in MPPT. However, the conventional control method is not suitable for moving vehicles’ PV, such as a solarcar. Therefore, the authors tested a generation characteristic of running state. In this study, The efficiency of Power Comparing Type and Hill Climbing Type MPPT systems is evaluated by outdoor running experiment. In Addition, it is not made clear about the detailed state for the generation characteristic on running time. So, we measured intergradation of real-time PV curve with a capacitor charge type I-V curve tracer. As a result, when the effect of shadow was intense, it was found that possibility of Power Comparing Method was useful.
