Title:
ELECTRICAL POWER SYSTEM FOR A SELF-CONTAINED TRANSPORTABLE LIFE SUPPORT SYSTEM
Document Type and Number:
WIPO Patent Application WO2000059444
Kind Code:
A9
Abstract:
A switching control circuit for use in an electrical power system for a transportable life support system is disclosed. The switching control circuit (114) provides uninterrupted power to a load of medical, and utility devices by switching between one of a set of converted external power voltages (99) and an internal power voltage outputted by a rechargeable internal power source (112). The power switching is effected within the time interval during which a residual voltage still remains on line due to capacitance discharge of the main bus (8) resulting in uninterrupted electrical power to the load.
