DUAL ISOLATED POWER SUPPLY INPUTS

摘要

A power supply system for providing power from either a first power supply 115 or a second power supply 160 to an ultimate rectified output 190. When the first power supply 115 is providing a voltage within a predetermined window and the first switch 125 is closed, the first power supply 115 provides an inhibit signal to the second switch 170 of the second power supply 160 that prevents the second power supply 160 from providing power to the ultimate rectified output 190. Similarly, when the second power supply 160 is providing a voltage within a predetermined window and the second switch 170 is closed, the second power supply 160 provides an inhibit signal to the first switch 125 of the first power supply 115 that prevents the first power supply 115 from providing power to the ultimate rectified output 190.
