PFC controller

22 February 2012 Power Electronics / Power Management

Analog Devices introduced the ADP1048, an interleaved digital PFC controller with highly accurate AC power metering capability. It can convert all signals to the digital domain and allow parameters to be adjusted and reported over a PMBus-compliant interface, including accurate measurement of input voltage, current and power. The device provides power metering accuracy of ±3% at full load current with further improvements to ±1% with customer calibration. It also offers enhanced transient response through non-linear control algorithms, programmable inrush control to reduce startup over-stress, real-time programming to maximise efficiency and extensive fault detection and reporting for improved reliability.
