High Power Factor

For the existence of a large input current harmonic content and the problem of low power factor, we propose an idea using APFC technical to design high power factor switching power supply to deal with it, meanwhile, the design process of APFC circuit parameters of the various components is given. Finally, the design proved to be correct and feasible by the simulation with Saber.

Street Lamp

This paper designs a type of intelligent switching power supply controller for LED street lamp. The configuration and principle of the controller is detailedly analyzed in this paper. Microprocessor PIC12F675 is employed in the design. With the controller, According to defferent illumination requirements, the controller achieves constant voltage and different constant LED current is automatically regulated to achieve energy saving without LED light intensity decrease notably. The controller is easy to be realized in circuit with high efficiency and high power factor.
