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.
