Abstract: A power system for multi-input devices with shared reserve power includes a first automatic transfer switch (ATS) and a second ATS each coupled at respective inputs to a primary power system and a reserve power system. An output of one of the ATSs is coupled to first power input of a multi-input electrical device and an output of the other ATS is coupled to a second power input of the multi-input electrical device. When primary power is available, electrical power is fed to both the inputs of the multi-input electrical device and when primary power is not available reserve power is fed to both inputs of the multi-input electrical device. If a component fails between the primary and/or reserve power system and the multi-input electrical device, a full load of the multi-input electrical device is fed from a non-affected one of the inputs of the multi-input electrical device.
