Abstract: A system and methods for providing substantially uninterrupted electric power to one or more critical loads that significantly allows superior utilization of equipment and physical space, as well as reduction in the environmental footprint of systems for providing substantially uninterrupted electric power to one or more critical loads. The system and methods comprise an arrangement of power modules configured for providing substantially uninterrupted electric power to one or more critical loads using a combination of loads. The combination of loads generally follows a detailed method that comprises grouping of loads and mathematically determining the power relationships between the power modules and one or more loads. Generally, the method comprises determining the characteristics of the power lines that deliver substantially uninterrupted electric power from the power modules to one or more critical loads. Further, the system may comprise a plurality of power delivery architectures.
