Control circuit and adjustment method for adjusting generator resistance according to driving force

Abstract

The invention discloses a control circuit and an adjustment method for adjusting the resistance of a generator according to the magnitude of the driving force, including a generator, a sampling module connected to the generator through a rectification module, and a rotational speed sampling module for collecting the rotational speed of the generator, respectively connected to the above-mentioned modules A control unit, the sampling module and the control unit are connected with a load adjustment module that controls the working resistance of the drive generator, and the control unit adjusts the resistance output of the load adjustment module according to the information collected by each module. The invention adjusts the corresponding driving resistance by understanding the current state of the generator, so that the driving force for driving the generator can always maintain an ideal state. Using the adjustment method of the present invention, it is possible to make targeted resistance adjustments under the specific conditions of the current driving force, and also provide corresponding operating environment settings according to the standards that the driving force needs to meet, so as to test the adaptation of the driving force and test the driving force the upper limit that can be achieved.
