Automatic power adapter

Abstract

An electrical device for automatically combining two supply circuits with aligned or unaligned phases, into a single operational circuit, with an output load capacity totaling approximately the sum of the two lower supply circuits. The device, through a series of relays and contactors, internally senses the phase alignment of the supply circuits, chooses the correct path, and automatically connects the supply circuits to the load circuit without the need of manual switches, or additional adapters.

1 . A device with automatic phase sensing, and automatic phase aligning capabilities, able to sense if the phases are aligned, and if unaligned to automatically align the phases internally, and safely connect the two lower amperage capacity circuits of the same or similar voltages into a single higher amperage capacity circuit without significant voltage change, to equal approximately the sum of the two lower amperage capacity circuits, such as 2 (two) 240 volt 50 amp circuits into 1 (one) 240 volt 100-amp circuit, automatically, or if the phases are aligned, to safely connect the two aligned lower amperage capacity circuits of same or similar voltages into a single higher amperage capacity circuit without significant voltage change to equal approximately the sum of the two lower amperage capacity circuits, such as 2 (two) 240 volt 50 amp circuits into 1 (one) 240 volt 100-amp circuit, automatically.  
   
   
       2 . An automatic adapter using (3) three or more contactors or (1) one or more reversing contactors to automatically switch or align the phases to adapt two lower amperage capacity circuits into a single higher amperage capacity circuit, equaling the approximate sum of the two lower amperage circuits.  
   
   
       3 . The stated voltages and amperages are used as examples only, and in no way limits the scope of the invention to specific values. A mechanical or electrical lockout can be used with contactors C 29  and C 30  for extra protection against both C 29  and C 30  engaging at the same time. The timer used in the drawings requires only two wires. The device can be wired with several different types of timers for similar results.
