System for controlling an electrical load

A system for controlling an electrical load, the system comprising:

• a first power converter and a second power converter connected in parallel, each of the first power converter and the second power converter including an inverter stage with an output connected to the electrical load;
• a first controller configured to control the inverter stage of the first power converter, the first controller including a first main control module configured to determine a first output voltage to be applied to the electrical load, the first output voltage being determined based on a first output current of the first power converter;
• and
• a second controller configured to control the inverter stage of the second power converter, the second controller including:
• a second main control module configured to determine a second output voltage to be applied to the electrical load, the second output voltage being based on a second output current of the second power converter, and
• a secondary control module configured to determine a correction voltage to be applied to the second output voltage, the correction voltage being determined based on a difference between the second output current of the second power converter and the first output current of the first power converter,
• wherein the first power converter and the second power converter are asymmetrical in terms of configuration and components in that the first power converter does not include a respective secondary control module configured to determine a correction voltage, to be applied to the first output voltage, the correction voltage being determined based on a difference between the second output current of the second power converter and the first output current of the first power converter.
