ABSTRACT:
Devices and methods for using multiple transformers to provide a power supply to a device or system. Included are systems for using multiple transformers and multiple fuses or circuit breakers to provide a power supply. In one embodiment two transformers and two fuses or circuit breakers are used to provide a power supply. Embodiments with greater numbers of fuses and transformers are also disclosed. Also illustrated are methods and devices using thermal circuit breakers to equalize current between multiple transformer sources or to compensate for differences between multiple transformers. Also included are switched schemes for assuring proper phasing of power supply transformers.
