Patent Images
1. A power supply circuit for driving a load with a first power source and with a second power source, comprising:
- (a) a switching network comprising a first switch and an interlock switch;
(b) a first circuit section for connecting the first power source to the load only when both the first switch and the interlock switch are on; and
(c) a second circuit section for connecting the second power source to the load only when both the first switch and the interlock switch are on, wherein the switching network provides isolation between the first and second circuit sections.

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.

7. A power supply circuit for driving a load with a first power source and with a second power source, comprising:
-
(a) a first circuit section for connecting the first power source to the load only when a first base terminal is not coupled to ground; (b) a second circuit section for connecting the second power source to the load only when a second base terminal is coupled to ground; and (c) a switching network comprising a single-pole double-throw first switch and a double-pole double-throw interlock switch having first and second interlock switches, wherein the first switch couples the first base terminal to ground in an off position and couples a switch node to ground in the on position;
the first interlock switch couples the first base terminal to ground only in an off position; and
the second interlock switch couples the switch node to the second base terminal only in an on position. - View Dependent Claims (8)
