Abstract
A circuit to power multiple load elements is presented. Fewer discrete components and fewer output terminals are required to power multiple devices. A single high-power DC boost circuit powers multiple AC devices. An end-user can selectively power a subset of the AC devices electrically connected to the present invention. The circuit includes a first and second reference voltage terminal, and a first, second, and third switch. The circuit also includes a first control switch and a second control switch in electrical communication with the first switch and the second switch, respectively. The first control switch provides either a first control signal or a second control signal to a control terminal of the first switch. Similarly, the second control switch provides either the first control signal or the second control signal to a control terminal of the third switch.
