NORWOOD, USA: Analog Devices Inc. (ADI) has introduced the ADP1048, the first interleaved digital power factor correction (PFC) controller with highly accurate AC power metering capability.
Similar to the ADP1047 single-phase digital PFC controller (announced March, 2011), the interleaved (or dual-phase) ADP1048 uses conventional, continuous-conduction-mode PFC techniques to reduce harmonic distortion. The ADP1048 can be configured as an interleaved design to reduce inductor size and replace the ACDC rectifier to improve efficiency in bridgeless boost mode.
These techniques 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 ADP1048 is extremely versatile and easy-to-use enabling ACDC designers and system architects to tweak their design in real-time and optimize efficiency at system level.
