SYSTEM AND METHOD OF A MOBILE ELECTRICAL SYSTEM

Abstract: an example system includes a dc/dc converter interposed between a battery pack and an electrical load of a vehicle, the dc/dc converter having a first power supply phase and a second power supply phase; and a controller, including: a power request circuit structured to interpret a power request for the electrical load; a power provision circuit structured to determine a current value for each of a plurality of power supply phases; and a power command circuit structured to provide a phase power command value in response to the current value for each of the plurality of power supply phases, the phase power command value including a duty cycle command for each of the plurality of power supply phases; and wherein each of the power supply phases are responsive to the phase power command value to provide pulse width modulated (pwm) electrical power to the electrical load.
