Abstract
The present disclosure relates to a shared hybrid transfer switch for transferring power received by a Load from a preferred AC power source to an alternate AC power source, or transferring power being received by the Load from the alternate AC power source to the preferred AC power source. The transfer switch makes use of a solid-state switch configured in communication with first and second pluralities of relay contacts, and also being coupled to the Load, and which receives control signals from a controller. The solid-state switch is controlled such that it is turned on to be in communication with select ones of the first and second pluralities of relay contacts, to provide a path for current flow to the Load from one of the preferred or alternate AC power sources being transitioned to, to carry out a switching transition from one of the preferred or alternate AC power sources to the other.
