摘要

This paper describes a dual feed high power boost DC/DC/AC converter in a single power module. The DC/DC converter section modulates both the positive and negative DC bus voltage of the AC inverter for traction motor applications in fuel cell and hybrid electric vehicles. Two boost converters are arranged in series and on either side of the DC bus to reduce voltage rating for the semiconductor switches in the boost converter. The topology utilizes six inductors, three for each boost converter, to share the input current and make it more feasible for packaging and thermal management. The higher DC bus voltage enables the efficient design of the traction inverter and motor for size, weight, reliability and cost.
