Abstract
A power supply system providing a power conversion function for a system circuit includes first, second and third convertor circuits respectively including plural switches and first, second and third inductors. The first and second convertor circuits are coupled to first and second power supplies respectively through first and second ports of the system circuit. A third power supply is coupled to a battery module and an internal load circuit. The plural switches are configured to correspondingly switch the first to third inductors to perform power conversion between the first to third power supplies and an internal power bus of the system circuit. The voltage of the internal power bus is configured to be higher than any voltage of the first to third power supplies, such that a current of the internal power bus is lower than a third current of the third power supply.
