Power system for multiple power sources
First Claim
1. A power system for powering one or more loads, the power system comprising:
- a plurality of power sources electronically coupled to the one or more loads, wherein each of the plurality of power sources is in electronic communication with each other power source of the plurality of power sources, and wherein at least one of the plurality of power sources is selected from a list of;
a fuel cell stack, a battery, a capacitor, a flow battery, a solar panel, and a wind turbine; and
a plurality of power conversion systems coupled to each corresponding respective one of the plurality of power sources and wherein each of said plurality of power conversion systems includes;
a DC to DC boost converter (DDBC) for converting power received from one or more of the plurality of power sources, the DDBC having a plurality of interleaved, isolated, fill-bridge DC-DC converters arranged in a Delta-Wye configuration and a multi-leg bridge.

Abstract
A voltage booster allowing for increased utilization of low voltage, high current, unregulated DC power (“LVDC source”), such as, but not limited to, fuel cells, batteries, solar cells, wind turbines, and hydro-turbines. LVDC generation systems employing a variable low voltage DC-DC converter of the present disclosure may be used without a power inverter in applications requiring high voltage DC inputs and can also allow for the employment of common, low cost, reliable, low voltage energy storage chemistries (operating in the 12-48VDC range) while continuing to employ the use of traditional inverters designed for high voltage power supplies. An embodiment of the DC boost converter includes a plurality of interleaved, isolated, full-bridge DC-DC converters arranged in a Delta-Wye configuration and a multi-leg bridge.
