A modular, scalable, multi-function, power quality system provides a modular and scalable power conditioning system for utility networks. A configurable frame is coupled to an electrical input and an electrical output. A plurality of functional slots each including a receiving connector are coupled to the frame. One or more unique function subsystems are coupled to selected functional slots. Each unique function subsystem includes one or more electrical components coupled to the receiving connector of selected functional slots configured to define functional capability associated with the one or more functional slots. A plurality of identical power modules are disposed in selected functional slots of each of the one or more unique function subsystems. A controller coupled to each of the power modules is configured to enable the power modules in predetermined functional slots of the one or more unique subsystems to perform a predetermined function associated with the electrical input or the electrical output.

A multi-function power regulator for prioritizing functions and allocating resources thereof, the multi-function regulator including a plurality of resources each having a resource capacity limit. The multi-function regulator also includes a shunt converter is configured to perform one or more shunt converter functions while consuming one or more of the resources, a series converter is configured to perform one or more series converter functions while consuming one or more of the resources. A control engine coupled to the shunt converter, the series converter, and a plurality of sensors, the control engine is configured to monitor and control the one or more shunt converter functions and the one or more series converter functions. The multi-function regulator also includes a priority control engine coupled to the control engine, the priority control engine is configured to set a priority order for performing the one or more shunt converter functions and/or the one or more series converter functions and configured to determine whether one or more resource capacity limits has been exceeded or not exceeded by the shunt converter functions and/or the series converter function and in response to one or more exceeded resource capacity limits adjust the operation of the shunt converter functions and/or the series converter based on the priority order such that the one or more resource capacity limits exceeded is no longer exceeded.

Multi-function power regulator for prioritizing functions and allocating resources thereof

A UPS includes an AC output, power factor control circuitry; and a DC bus coupled to the power factor control circuitry where the power factor control circuitry is configured to determine a difference in instantaneous power supplied to the AC output and to adjust a voltage of the DC bus based, at least partly, on the difference. In one embodiment, the UPS includes a single phase AC input. In another embodiment, the power factor control circuitry is configured to determine a cumulative difference in instantaneous power supplied to the AC output.
