Abstract:
1. An electric architecture for use on a vehicle comprising: a collector bus for receiving power from a plurality of power sources, said collector bus distributing power to at least a pair of subsystems which are each operating at different frequency levels, and each of said subsystems being provided with a global bus and a local bus, and being utilized to power at least one motor; and each of said pair of subsystems is provided with a pair of inverters, a first inverter providing constant voltage and constant frequency, a second inverter providing variable voltage and variable frequency, and a plurality of switches controlled to use said second inverter, to provide power to said at least one motor at start-up, and until said at least one motor reaches a predetermined speed at which time said switches are changed such that power flows to said at least one motor through said first inverter, and such that said second inverter powers the local bus, while said first inverter powers the global bus.
