Abstract
Various systems are provided for a power supply system. In one example, the system includes a power distribution unit configured to receive power from a main power source and an uninterruptible power supply (UPS), wherein the UPS is configured to directly power an output AC load, the UPS is further configured to power an output DC load after coupled through one or more transformers.
Claims11
A system, comprising:
- a power distribution unit configured to receive power from a main power source and an uninterruptible power supply (UPS), wherein the UPS is configured to directly power an output AC load, the UPS is further configured to power an output DC load after coupled through one or more transformers, wherein the UPS is configured to power the output DC load via passing current through a primary transformer, a first secondary transformer, and a second secondary transformer;
- a main input contactor coupled between the main power source and the primary transformer and configured to be in an open position to block current between the primary transformer and the main power source responsive to power from the main power source being interrupted and/or unavailable;
- and
- an interlock switch coupled between the second secondary transformer and the UPS, the interlock switch having a power-to switch and a power-from switch, wherein the power-to switch is configured to be in an open position to block current between the second secondary transformer and the UPS responsive to power from the main power source being interrupted and/or unavailable.

A medical imaging system, comprising:
- a gantry coupled to an output DC load;
- a power cabinet coupled to an output AC load;
- a power distribution unit (PDU) comprising a primary transformer, a first secondary transformer, and a second secondary transformer;
- wherein the power distribution unit is configured to receive power from one of a main power source and an uninterruptible power supply (UPS);
- a main input contactor coupled between the main power source and the primary transformer;
- an interlock switch coupled between the second secondary transformer and the UPS, the interlock switch having a power-to switch and a power-from switch;
- and
- a controller with computer readable instructions stored on memory thereof that cause the controller to:
- adjust a position of the main input contactor and the power-to switch to an open position in response to power from the main power source being interrupted and/or unavailable;
- and
- adjust a position of the power-from switch to a closed position to couple power from the UPS to the output AC load and the output DC load.
