Integrated modular electric power system for a vehicle
First Claim
1. A power system architecture for a vehicle comprising:
- a source management unit including at least a generator, a first stored energy component, and a second stored energy component;
a high voltage DC bus connecting a high voltage load to said source management unit;
at least one low voltage DC bus connecting at least one low voltage DC load to the source management unit;
the source management unit including a plurality of multi-functional power modules configured such that the source management unit includes a multi-level active rectifier connecting the generator to a multi-level DC bus, a first multi-level multi-function converter connecting the first stored energy component to the multi-level active rectifier, a second multi-level multi-function converter connecting the second stored energy component to a multi-level isolated DC bus, and an isolated multi-level DC-DC converter connecting the multi-level DC bus to the multi-level isolated DC bus.

Abstract
A power system architecture for a vehicle includes a source management unit having at least a generator, a first stored energy component, and a second stored energy component. A high voltage DC bus connects a high voltage load to the source management unit. At least one low voltage DC bus connects at least one low voltage DC load to the source management unit. The source management unit includes a plurality of multi-functional power modules configured such that the source management unit includes a multi-level active rectifier connecting the generator to a multi-level DC bus, a first multi-level multi-function converter connecting the first stored energy component to the multi-level active rectifier, a second multi-level multi-function converter connecting the second stored energy component to a multi-level isolated DC bus, and an isolated multi-level DC-DC converter connecting the multi-level DC bus to the multi-level isolated DC bus.
