Abstract
Methods and apparatus are provided for controlling a boost converter. In one embodiment, the method includes processing an input current command through a plurality of prioritized limiting circuits to determine whether to limit the input current command and limiting the input current command to limit the boost converter when it is determined to limit the input current command. In one embodiment, the apparatus includes an energy source coupled to a boost converter that provides an output voltage responsive to a current command signal. An inverter is coupled to the boost converter to provide multiple phased currents to a multi-phase motor for a vehicle. A controller coupled to the boost converter for providing the current command signal by processing an input current command through a plurality of prioritized limiting circuits and determining whether to limit the input current command to provide the current command signal to the boost converter.
