In order to improve the car vacuum cleaner, security and reliability of power supply device in practical applica-tion, the realization of the aim of small volume and more function, the effective use of the advantages of the RCD active clamp circuit, and presents a continuous model (CCM) based on the current control of single-ended flyback type vehicle vacuum cleaner power supply devices, and analyzed the related theory. Using the UC3842 digital chip as control circuit of the controller, and the control circuit of multiple components were set up by calculation. Finally on the 5 v output of no load and full load experiment, the experimental results show that the vehicle vacuum cleaner power supply devices working con-dition is good, the output voltage stability, high reliability and good applicability. At the same time, also the problems oc-curred in the experiment of several solutions are given.
