Abstract
Abstract An electrical interconnection system (100) comprises a rotary converter (102) and a controller (104). The rotary converter (102) is coupled to first and second electrical systems having a differing electrical characteristic (e.g., frequency or phase). The controller (104) bidirectionally operates the rotary converter (102) at a variable speed for transferring power from the first electrical system to the second electrical system.
