Abstract:
Wind energy based power generation has
become one of the focal points in the research of renewable
energy sources. Mobile phones are essential communication
devices nowadays but still people face difficulties in mobile
phone charging where the utility supply is not available. This
paper presents a design and implementation of a small scale
low speed wind power based portable mobile phone charger.
The implementation includes a savonius wind turbine and a
controller. According to the speed change of the wind, the
output voltage of the generator changes from 1V to 3V so a
controller is designed to control a DC-DC boost converter to
get a constant output voltage. The formal approach of the PI
control scheme is used in the design of the controller. The
integrated device is able to produce the desired output
voltage to charge the mobile phone. This device provides
green energy for mobile phone charging where the utility is
not available.
