ABSTRACT:
A power supply circuit drives a load with first and second power sources. The power supply circuit has a switching network comprising a first switch and an interlock switch. A first circuit section connects the first power source to the load only when both the first switch and the interlock switch are on, and a second circuit section connects the second power source to the load only when both the first switch and the interlock switch are on. The switching network provides isolation between the first and second circuit sections.
