A system for reducing power loss in a medical apparatus may include multiple power sources, a power source switch matrix, a diode, and a diode bypass switch. The power source switch matrix may control whether each power source is currently providing power to the power load. The diode may be electrically coupled to a first power source to prevent current from one or more of the other power sources from being applied to the first power source. The diode bypass switch may be coupled to the first power source and is operable to switch between a first state in which a current pathway from the first power source to the power load includes the diode and a second state providing a current pathway from the first power source to the power load that circumvents the diode.
