Abstract
A power generation system comprises at least two electrical systems connected at an electrical connection point. Each electrical system comprises a power conversion system comprising a converter including a plurality of switches for converting direct current power into alternating current power. The power generation system comprises a control system including at least two pulse width modulation (PWM) modulators, each PWM modulator for obtaining a fundamental waveform and a carrier signal, using the fundamental and carrier signals to generate a PWM pattern, and for providing the PWM pattern to a respective converter for driving the switches of the respective converter. The control system is configured to interleave carrier signals, fundamental waveforms, or a combination of carrier signals and fundamental waveforms of the at least two electrical systems to generate interleaved PWM patterns respectively for the at least two converters.
