Abstract: A system for controlling one or more loads. The system comprises a plurality of power converters, wherein each power converter is configured to be arranged in a parallel configuration with one or more additional power converters so as to control the one or more loads, and a central controller configured to output a common reference based on local current or voltage values received from each power converter; and transmit the common reference to each of the power converters. Each power converter comprises an inverter configured to control the one or more loads based on voltage switching signals, a module configured to provide the voltage switching signals to the inverter according to a modulation scheme.

Abstract: There is provided a system for providing (e.g., configured to provide) power to one or more loads. The system comprises a plurality of power converters, wherein each power converter is configured to be arranged in a parallel configuration with one or more additional power converters so as to provide power to the one or more loads. The system further comprises a central controller configured to receive a plurality of local current measurement values from each of the power converters, output a global current measurement value based on the local current measurement values, and transmit the global current measurement value to each of the power converters, wherein each power converter comprises an inverter for receiving an input voltage and converting this to an output voltage having one or more associated output current(s).

Abstract: A proportional integrator for control of a motor drive arranged to be connected in parallel with one or more other motor drives to drive a common load. The proportional integrator includes means to receive an input command signal and to compare with a local measured signal from the motor drive and to output a local control signal for that motor drive, further comprising a global input signal indicative of the behaviour of the one or more other motor drives, the global input signal being incorporated into the proportional integral function with the input command signal and the local measured signal to provide the local control signal.
