摘要： Methods and systems are provided for control operation of a boost converter. The boost converter includes an input, an output, and a plurality of paths electrically connecting the input to the output. The boost converter also includes a plurality of switches disposed along the paths to control current flow between the input and the output. The system includes a controller. The controller receives a desired current to be supplied at the output. The controller determines which of the paths to utilize based at least in part on the desired current. The controller controls the switches based at least in part on the determination of which of the paths to utilize.
