Designed a prototype of DC auxiliary power supply composed of the constant current module and voltage regulator module. Introduced the working principle of DC auxiliary power supply circuit, designed a prototype of DC auxiliary power supply, and tested the change of output voltage in the voltage fluctuation of the grid and the load variation. The result indicates that the prototype creates a stable output voltage of 12 V with 220 V AC power accessed, and the performance meets the design requirement.
