The invention discloses a voltage adjusting circuit. The voltage adjusting circuit comprises a drive circuit, a time sequence resistance control circuit, a resistance adjusting circuit, a frequency conversion voltage adjuster and a power circuit, wherein the driving circuit is used for sending a driving signal; the time sequence resistance control circuit is connected with the driving circuit and used for generating a resistance control signal by using the driving signal; the resistance adjusting circuit is connected with the time sequence resistance control circuit and used for supplying a variable resistance to the voltage adjusting circuit under the control of the resistance control signal; the frequency conversion adjuster is connected with the resistance adjusting circuit and is used for generating an adjustable voltage according to the variable resistance; the power circuit is connected with the drive circuit and used for supplying power to the voltage adjusting circuit through an electric energy control signal of the drive circuit. In the embodiment of the invention, the problem of the prior art that the efficiency of voltage stability test is low since different voltages cannot be automatically generated is solved, and the effect of rapidly and efficiently automatically adjusting the voltage is achieved.
Description
technical field [0001] The invention relates to the field of voltage control, in particular to a voltage regulating circuit. Background technique [0002] At present, the company develops a variety of models with PG motor (a motor whose speed is controlled by the conduction angle of the thyristor) or DC motor, and the speed of each model corresponding to the hat number is inconsistent. The cap number is a design method to distinguish the size of the model. There are 30 caps in one controller, which can be selected by yourself. For example, in the design of a certain model, it is defined that the No. The number cap is 50 models, etc. The motor speeds of each model are inconsistent. When verifying the stability of the motor at different voltages, it is necessary to artificially build different circuits to produce different The voltage is used to verify the stability of the motor at different voltages. It can be seen from the above that we need to spend a lot of manpower and m...
