A circuit for regulating power between a first power source, a second power source, and a load is disclosed. The circuit includes a first switch electrically coupled to a second switch, where the first switch and the second switch are arranged relative to one another to block current in opposing directions when opened. The first switch is electrically coupled to the first power source and the second switch is electrically coupled to the load. The circuit also includes third switch electrically coupled to a fourth switch, where the third switch and the fourth switch are arranged relative to one another to block current in opposing directions when opened. The third switch is electrically coupled to the second power source and the fourth switch is electrically coupled to the load and the second switch. The circuit also includes a first voltage sensor, a second voltage sensor, a first current flow sensor, and a second current flow sensor.
