Abstract
Embodiments of this present disclosure may include a system with a first power converter and a control system. The first power converter may supply a first output power to a first backplane at least sometimes concurrent to a second power converter supplying a second output power to a second backplane. The control system may be electrically coupled to the first backplane and the second backplane. The control system may balance a first electrical property and a second electrical property provided to each of one or more load components electrically coupled to the first backplane and the second backplane.
Claims20
A system, comprising:
- a first power converter configured to supply a first output power;
- a second power converter configured to supply a second output power
- a first backplane electrically coupled to the first power converter and the second power converter;
- a second backplane electrically coupled to the first power converter and the second power converter;
- one or more load components each comprising a first ORing circuit and a second ORing circuit electrically coupled to the first backplane and the second backplane, respectively, and configured to operate based on the first output power, the second output power, or both;
- and
- a control system communicatively coupled to the first power converter, the second power converter, and one or more sensors, wherein the control system is configured to:
- receive a first indication of the first output power from the one or more sensors;
- receive a second indication of the second output power from the one or more sensors;
- determine a difference between the first output power and the second output power;
- determine that the difference is greater than or equal to a threshold amount of power;
- and
- in response to the difference being greater than or equal to the threshold amount of power, send one or more control signals to the first power converter, the second power converter, or both to adjust the first output power, the second output power, or both based on the difference.

A system, comprising:
- a first power converter configured to supply a first power output;
- a second power converter supplying a second power output;
- a first backplane electrically coupled to the first power converter and the second power converter;
- a second backplane electrically coupled to the first power converter and the second power converter;
- and
- a control system electrically coupled to the first power converter and the second power converter, wherein the control system is configured to balance the first power output and the second power output provided to each of one or more load components, wherein the one or more load components each comprise a first ORing circuit and a second ORing circuit electrically coupled to the first backplane and the second backplane, respectively.

A method, comprising:
- receiving, via a power conditioner control system configured to electrically couple to a first backplane and a second backplane, a first indication of a first output power from one or more sensors, wherein a first power converter is configured to supply the first output power, and wherein each of one or more load components comprises a first ORing circuit and a second ORing circuit electrically coupled to the first backplane and the second backplane, respectively;
- receiving, via the power conditioner control system, a second indication of a second output power from the one or more sensors, wherein a second power converter is configured to supply the second output power;
- determining, via the power conditioner control system, a difference between the first output power and the second output power;
- determining, via the power conditioner control system, that the difference is greater than or equal to a threshold amount of power;
- and
- in response to the difference being greater than or equal to the threshold amount of power, sending, via the power conditioner control system, one or more control signals to the first power converter, the second power converter, or both to adjust the first output power, the second output power, or both based on the difference.
