First Claim
Patent Images
1. A power distribution system comprising:
- a power source side;
a load side; and
a plurality of power converters on each of the power source side and the load side, wherein at least the load side converters are each configured to provide a modular stacked dc converter architecture, and further wherein the load side converters are each configured with a respective energy storage system such that together the plurality of energy storage systems deliver energy to a common control system busbar.
