Abstract

A High Efficiency Power Factor Correction (PFC) Circuit For AC/DC Adapters Problem: The ac -dc adapters required for mobile products require very high efficiency and small size. The ac -dc adapter so far has not required any power factor correction. However, there is a trend to require power factor correction for these low power ac -dc adapters. Also. the existing methods for power factor correction are not suitable because of the size limitation. D11 R2
