Recently proposed power packet (PP) distribution system can reduce stand-by power, improve the traditional power distribution system efficiency using less power processing stages, and monitor load demand intelligently from source side to keep the power system stable. Each PP includes header and footer bits which are used to distribute the PP. Reduced footer bit can save the transitional switching loss. A modified PP format with reduced footer bit and an improved algorithm to route the PP to the objective loads are proposed in this paper and verified by the experimental results.
