Abstract
A solid-state automatic transfer switch includes a primary rectifier circuit and a secondary rectifier circuit, wherein at least one of the rectifier circuits includes one or more controllable semi-conductor switches. The primary rectifier circuit is electrically coupled to a primary input and an output of the solid-state automatic transfer switch. Also, the secondary rectifier circuit is electrically coupled to a secondary input of the solid-state automatic transfer switch and the output. A controller controls a control state of the controllable semi-conductor switches to allow or prevent electrical power from flowing through the primary or secondary rectifier circuits, thus selectively controlling whether power is fed from the primary input or the secondary input of the solid-state automatic transfer switch to the output of the solid-state automatic transfer switch.
