Texas Instruments

Published Date: 09/05/1999

Description

The UC3852 provides a low-cost solution to active power-factor correction (PFC) for systems that would otherwise draw high peak current pulses from AC power lines. This circuit implements zero-current switched boost conversion producing sinusoidal input currents with a minimum of external components while keeping peak current substantially below that of fully-discontinuous converters.
