Digital Power Factor Correction Controller with Accurate AC Power Metering ADP1047/ADP1048
GENERAL DESCRIPTION
The ADP1047/ADP1048 are digital power factor correction (PFC) controllers that provide accurate input power metering capability and inrush current control for ac/dc systems. The ADP1047 is designed for single phase PFC applications; the ADP1048 is designed especially for interleaved and bridgeless PFC applications. The digital PFC function is based on a conventional boost PFC with multiplication of the output voltage feedback bined with the input current and voltage to provide optimum harmonic correction and power factor for ac/dc systems. All signals are...
