Abstract
The present invention relates a method for optimizing electrical current in a DC link busbar of a power converter system, wherein the power converter system comprises, a first inverter bridge, connected to the DC link busbar at a first end, the first inverter bridge having a first pulse width modulation signal, and a second inverter bridge, connected to the DC link busbar at a second end, the second inverter bridge having a second pulse width modulation signal, measuring a current flowing in the DC link busbar from the first end to the second end, optimizing the current flowing in the DC link busbar by delaying the first pulse width modulation signal and the second pulse width modulation signal from each other with a carrier delay, the invention also relates to power converter and wind turbine with optimizing electrical current in a DC link busbar.
