ADI ADP1047数字PFC控制方案
ADI 公司的ADP1047是业界首个具有能量测量的数字功率因素修正(PFC)控制器。
The ADP1047 is a digital power factor correction controller providing accurate input power metering capability and inrush control targeting ac/dc systems.
The digital PFC function is based on a conventional boost PFC with multiplication of the output voltage feedback combined with the input current and voltage to provide optimum harmonic correction and power factor for ac/dc systems. All signals are converted into the digital domain to provide maximum flexibility—all key parameters can be reported and adjusted via the PMBus interface. This allows users to optimize system per-formance, maximize efficiency across the load range, and reduce design time to market.
The ADP1047 provides accurate, rms measurement of input voltage, current and power. This information can be reported to the secondary of the power supply via the PMBus interface.
