Title The design of minitype household wind-driven generator controller
Abstract
The utilization of regenerative energy plaise an important flat on ours socioeconomic sustainable development and environmental protection.Wind energy is used widly.For the moment,we storage energy using accumulator for the minitype wind-driven generator.The accumulator supplies energy for the electric appliance.When the accumulator discharged its energey, it can be supplised by the wind-driven generator in season.Owing to the randomness of the wind energy and the big excursion of the wind speed,it makes the accumulator charging difficulty.The theses givise out a sort of accumulator charging arrangement of controls.The design clue of the theses is:sampling the accumulator’s charging current and charging voltage with sensor and sample circuit,the SCM ascertains the accumulator’s charged state according to the sampled signal.Then,the SCM discharge homologous D/A signal.The PWM control integration chip brought homologous PWM impulse,which can drove the MOSFET in the charge up circuit.Thereby,it can regulate the charging current,guaranting the accumulator can be charged in security and apace.
