摘要：A digital average-input current-mode control loop for a DC/DC power

converter. The power converter may be, for example, a buck converter, boost converter,or cascaded buck-boost converter. The purpose of the proposed control loop is to set

the average converter input current to the requested current. Controlling the averageinput current can be relevant for various applications such as power factor correction(PFC), photovoltaic converters, and more. The method is based on predicting the inductorcurrent based on measuring the input voltage, the output voltage, and the inductorcurrent. A fast cycle-by-cycle control loop may be implemented. The conversion methodis described for three different modes. For each mode a different control loop is used tocontrol the average input current, and the control loop for each of the different modes isdescribed. Finally, the algorithm for switching between the modes is disclosed.
