Patent ID: 11881773
Assignee: SCHNEIDER ELECTRIC IT CORPORATION
Field: Electrical machinery, apparatus, energy (Electrical engineering)
Classification: CPC H  Y | IPC H

Claim 0:
1. A power circuit comprising:
an input configured to be coupled to an input source and to receive input power from the input source;
a first output configured to provide output power to a load;
a second output configured to provide output power to a controller;
a Logic Power Supply (LPS) coupled to the input and configured to convert the input power into LPS output power;
a first switch configured to couple the LPS to the first output in a first mode of operation and to decouple the LPS from the first output in a second mode of operation, the LPS further configured to provide, in the first mode of operation, the LPS output power with a first voltage level to the first switch in response to receiving an indication that the load is being powered by the LPS output power and configured to provide, in the second mode of operation, the LPS output power to the first switch with a second voltage level in response to receiving an indication that the load is not being powered by the LPS output power, the second voltage level being generated by the LPS based on a level sufficient to power the controller; and
a converter coupled to the LPS and the second output, the converter configured, in the second mode of operation, to convert the LPS output power with the second voltage level into converter output power and provide the converter output power to the controller via the second output to power the controller,
wherein the second output is disconnected from the first output such that the second output does not provide power to the first switch.
