First digital PFC controller with power metering

First digital PFC controller with power metering

The ADP1047 is the industry’s first digital PFC controller with ac power meter capability and inrush control functionality. It targets ac/dc power-factor correction and precision power-metering applications that require high reliability and redundant power supplies, such as communications infrastructure and motor control.

The digital PFC controller uses conventional, continuous-conduction mode PFC techniques. All signals are converted to the digital domain, allowing parameters to be adjusted and reported over a PMBus-compliant interface, including RMS measurement of input voltage, current and power. It helps optimize system harmonic performance, maximize efficiency across the load range. (Samples and evaluation boards, available April; full production, scheduled for July.)
