Abstract: A control circuit is described herein. The control circuit includes an oscillator and a processor. The oscillator is configured to generate a reference signal. The processor is coupled to the oscillator. The processor is configured to receive a first output current sample, a second output current sample, and a third output current sample, all of an output current. The first output current sample is first-in-time, the second output current sample is second-in-time, and the third output current sample is third-in-time. The processor is further configured to compute a time-derivative of the output current. The processor is further configured to compute a command variable based on the reference signal, a time-derivative of the reference signal, the third output current sample, and the time-derivative of the output current.

Abstract: A grid interactive uninterruptible power supply (UPS) is provided. The grid interactive UPS includes a first path including a rectifier, an inverter coupled in series with the rectifier, and a battery coupled in parallel with the inverter. The grid interactive UPS further includes a second path in parallel with the first path, wherein the grid interactive UPS is operable to supply power from the battery to a grid coupled to an input of the grid interactive UPS.
