Abstract
A head end power (HEP) system for a locomotive is disclosed. The HEP system may include a first HEP inverter module operatively connected between a direct current (DC) link and a transformer, and a second HEP inverter module operatively connected between the DC link and the transformer in parallel with the first HEP inverter module. The first HEP inverter module and the second HEP inverter module may be configured to convert power from the DC link into an alternating current (AC). The transformer may be configured to transfer power from the first HEP inverter module and the second HEP inverter module to a HEP bus.
