Abstract
This paper uses the Bridgeless Rectifier Circuit, coupled with the Interleaved Boost and “PFC” (Power Factor Correction) technology to design a high-efficiency AC/DC conversion circuit, to provide a load of 400V, 2KW. The system efficiency can reach up to 96%. The power factor is close to 1, the input current ripple is below 0.8A and the output voltage ripple is below 6V. In addition to the application in variable- frequency control air-conditioning, the proposed system can also be used for a wide range of variable frequency control motors and DC electric motors, such as household fans, DC electronic fluorescent lamps or variable- frequency control motors.
