Propulsion system for a motor vehicle using a bidirectional energy converter
First Claim
1. A motor vehicle propulsion system comprising:
- an electrical energy source;
a traction motor coupled to receive electrical energy from said electrical energy source;
a first bus provided electrical energy by said electrical energy source;
a second bus of relatively lower voltage than said first bus;
an electrically-driven source of reaction gas for said electrical energy source, said source of reaction gas coupled to receive electrical energy from said first bus;
means coupled to said second bus for storing electrical energy at said lower voltage; and
a bidirectional energy converter coupled to convert electrical energy from said first bus to said second bus and from said second bus to said first bus.

Abstract
A motor vehicle propulsion system includes an electrical energy source and a traction motor coupled to receive electrical energy from the electrical energy source. The system also has a first bus provided electrical energy by the electrical energy source and a second bus of relatively lower voltage than the first bus. In addition, the system includes an electrically-driven source of reaction gas for the electrical energy source, the source of reaction gas coupled to receive electrical energy from the first bus. Also, the system has an electrical storage device coupled to the second bus for storing electrical energy at the lower voltage. The system also includes a bidirectional energy converter coupled to convert electrical energy from the first bus to the second bus and from the second bus to the first bus.
