Research of Super Capacitor Charging and Discharging System Based on DSP28335

The application of new energy resources such as wind power gets more and more attention, with the environmental problems and energy issues have become increasingly prominent. But the volatility and the characteristics of intermittent has greatly restricted the efficient utilization of the new energy. This paper designed a control circuit, the super capacitor as the energy storage device and the 28335 as the core. This circuit controls the charging and discharging of the super capacitor through the system sampling by 28335, so as to realize to the instantaneous compensation effect on the power fluctuation of the grid connected wind turbine, smooth wind farms output power and voltage. Apply this method by super-capacitor and TMS320F28335, we can provide a useful reference and efficient application of new energy.
