An electric power system includes a centralized switched mode power supply (SMPS) and a network bridge. The centralized SMPS includes AC/DC PFC power converters, DC/DC power converters and a control circuit having a communication interface. The control circuit is configured to control power switch(es) of the AC/DC PFC power converters and power switch(es) of the DC/DC power converters. The network bridge is in communication with the communication interface for receiving remote access control commands between a device remote from the centralized SMPS and the control circuit for controlling the power switch(es) of the AC/DC PFC power converters and the power switch(es) of the DC/DC power converters. Other example electric power systems and methods of detecting when at least one of a plurality of LED strings malfunctions in an electric power system are also disclosed.

Electric power systems including centralized switched mode power supplies

A horticulture facility includes a first set of LED luminaires disposed in a grow room of the horticulture facility, a second set of LED luminaires disposed in another grow room of the horticulture facility, a centralized power supply and power transfer switches. The power supply includes DC/DC power converters each having an output. The power transfer switches include a first power transfer switch coupled to the output of one respective DC/DC power converter of the DC/DC power converters. The first power transfer switch is configured to switch between a first position for coupling the output of the respective DC/DC power converter to the first set of LED luminaires, and a second position for coupling the output of the respective DC/DC power converter to the second set of LED luminaires. Other example horticulture facilities and electric power systems are also disclosed.
