| Summary: | 碩士 === 國立臺北科技大學 === 電力電子產業研發碩士專班 === 99 === This thesis is focused on the design and implementation of a 1000-W two-phase interleaved boost power factor corrector (PFC) with UC3854AN available from Texas Instruments and the associated mono-stable multi-vibrator HEF4528BP. The power stage consists of two Boost PFCs, which can greatly reduces the current ratings of the power switches and sizes of filter components, and further improve input current ripple.
The specifications of the implemented interleaved boost PFC include input voltage 220+/-20V, output voltage 400V and maximum output power is 1000W. From the experimental results, the power factor reaches 0.98 under full load condition and the efficiency is up to 90%.
