According to harmonics pollution and low power factor problems of the traditional switching power, the design is a switching power of high power factor based on UCC28019 chip used on 3D printers. This design has the advantages of high power factor, high efficiency, low harmonics and low noise. Main circuit passes through EMI filtering, full-bridge rectifier and then filter, Boost chopper boost and correction of active power factor and closed-loop controlling, making the output voltage stable, small interfering and high over-all efficiency.

This paper presents the design and development of a fuzzy peak current controlled (FPCC) single-stage single-phase nonisolated AC/DC high-power factor LED drive. The proposed controller includes a fuzzy logic controller (FLC) in the loop voltage and a peak current controller in the loop current for an integrated nonisolated LED driver to attain a high-power factor (PF). The proposed control avoids complexities related to nonlinearities of the converter. The control action is initially derived from a group of rules written in accordance with experience and intuitive reasoning. The proposed technique is realized using a DSP processor (TI-TMS320F2812), which is capable of executing a high number of instructions in one cycle. A 70 W, 350 mA LED driver operating with an input of 90 V-230 V, 50 Hz was designed and implemented using MATLAB/Simulink. The results of the driver are in accordance with international regulations. The steady-state and transient responses are validated experimentally.
