Abstract


The extensive use of power electronic devices bring serious harmonic pollution to the utility grid , causing a lot of unnecessary power consumption, to solve the harmonic pollution has received increasing attention . Power factor correction (Power Factor Correction, referred to as : PFC ) technology is to improve the power factor of electronic products , one effective way to reduce the harmonic pollution , it makes the power factor is almost up to more than 0.99 , it is widely used in a variety of power electronics device. Design a small power devices for lighting equipment Active Power Factor Correction (Active Power Factor Correction, : APFC) control chip XD7028 . The chip operates in critical conduction mode , voltage mode control , multipliers , simple structure , low power consumption . Designed for different national grid voltage dual output function that automatically adjusts the output based on the grid voltage , increase the range of applications . Analysis and improvement of traditional CMOS drive circuit in the the XD7028 design process , the design of a low power consumption , fast response, small layout area of the drive circuit . The peripheral circuit Boost topology structure calculations and design parameters of various peripheral devices . Finally, the EMI filter design . And Hspice / Cadence software using 0.35μBCD process models , simulation of the chip within the module and overall . Simulation results show that the indicators meet the design requirements of the chip , and has the power correction control performance .
