Abstract
In one aspect, a transfer switch configured to operate in different transfer modes is provided. The transfer switch includes first and second inputs, first and second contactors, an output, first and second power stages, and a controller. The first and second inputs are configured to couple with first and second power sources, respectively. The first and second contactors are configured to selectively couple with the first and second inputs, respectively. The output is configured to couple with a load. The first and second power stages are configured to conduct electrical power when active. The controller is configured to determine whether a trigger condition has occurred while the first power stage is active, and in response thereto, to open the first contactor and activate the second power stage to transfer the load from the first power source to the second power source.
