  • U-132 Power Factor Correction Using UC3852 Controlled On-Time Zero Current
    PDF, 323 Kb, Datei veröffentlicht: Sep 5, 1999
    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. The contro
