This paper describes design and characteristics of maximum power point tracking method (MPPT) for a new mobile charging system powered by a single solar cell. To reduce the power consumption of the system, we investigated variation of the MPPT algorithm. We applied a modified Constant Voltage method (CV) instead of Perturb and Observe method (P&O). Generated power using these methods is three times larger than that of non-MPPT system. Moreover, the power consumption of the CV method has decreased 20% compared to the P&O method.
