ELECTRIC DRIVE SYSTEM FOR MINING HAUL TRUCK

摘要

An electric drive system for a vehicle includes a first generator in communication with a first engine, a second generator in communication with a second engine, a first rectifier and a second rectifier. Each generator has a main winding, each main winding being independently excitable and generating an alternating current (AC) output. A main AC output of the main winding of the first generator is in communication with the first rectifier, and a main AC output of the main winding of the second generator is in communication with the second rectifier. When in drive mode, the first engine drives the first generator and the second engine drives the second generator, and the first and second generators supply power to a plurality of inverters coupled to the first and second rectifiers, the plurality of inverts supplying power to a plurality of electric wheel motors.
