There is provided a system for providing 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, and a central controller configured to receive a plurality of local voltage reference values from each of the power converters, output a global voltage reference value based on the local voltage reference values, and transmit the global voltage reference value to each of the power converters. 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); a control loop configured to output a local voltage reference value for transmission to the central controller, wherein the local voltage reference value is based at least in part on the output current value(s) of the inverter; and a module configured to modulate the output voltage of the inverter using one or more modulation schemes, wherein the modulation module receives as an input the global voltage reference value and is configured to regulate the output current(s) of the inverter based on the global voltage reference value.
