Abstract
Certain exemplary embodiments can comprise a system comprising an electric drive system for a machine. The system can comprise a rectifier adapted to convert AC power from an alternator to DC power. The system can comprise an inverter adapted to receive DC power from the rectifier and provide power to a traction motor and/or auxiliary devices. Certain exemplary embodiments can comprise a system and method for dissipating excess energy from a machine.
Claims22
A method comprising:
- at an auxiliary power system for an off-road traction vehicle, comprising:
- via an active Insulating Gate Bipolar Transistor rectifier, converting a first AC signal to a DC signal and providing the DC signal to a DC bus;
- via an active Insulating Gate Bipolar Transistor inverter electrically coupled to the DC bus, converting the DC signal to a second AC signal and providing the second AC signal to an auxiliary device;
- and
- receiving the DC signal at an active Insulating Gate Bipolar Transistor DC chopper, the active Insulating Gate Bipolar Transistor DC chopper electrically coupled to the DC bus.
