Control circuit enabling resistance of electric generator to be adjusted according to driving force and adjusting method

Abstract

The invention discloses a control circuit enabling the resistance of an electric generator to be adjusted according to the driving force and an adjusting method. The control circuit enabling the resistance of the electric generator to be adjusted according to the driving force comprises an electric generator, a sampling module connected with the electric generator through a rectifying module, a rotating speed sampling module used for collecting the rotating speed of the electric generator and a control unit respectively connected with the modules mentioned above. A load adjusting module used for controlling the resistance driving the electric generator to work is connected between the sampling module and the control unit. Resistance output of the load adjusting module is adjusted through the control unit according to collected information of each module. According to the control circuit enabling the resistance of the electric generator to be adjusted according to the driving force, the current state of the electric generator is known, so that corresponding driving resistance is adjusted, and the driving force driving the electric generator is kept in the ideal state all the time. Due to the adoption of the adjusting method, under the condition that the specific condition of the current driving force is known, pertinent resistance adjustment can be conducted, corresponding operation environment set can further be conducted according to the standard which the driving force needs to meet, and therefore the adapting condition of the driving force and the upper limit of the driving force can be tested.
