Abstract
A double ended inverter system for an AC traction motor of a vehicle includes a fuel cell configured to provide a DC voltage, an impedance source inverter subsystem coupled to the fuel cell, a DC voltage source, and an inverter subsystem coupled to the DC voltage source. The impedance source inverter subsystem, which includes an ultracapacitor, is configured to drive the AC traction motor. The inverter subsystem is configured to drive the AC electric traction motor. The ultracapacitor is implemented in a crossed LC network coupled to the fuel cell.
