6 FAQs about [And designing the power system rectifier of the generator]
What happens if a rectifier is used in an excitation system?
In an excitation system employing the rectifier, irrespective of whether it is supplied by an AC exciter or an excitation transformer, the AC phase currents of the rectifier will also be distorted into a non‐sinusoidal waveform in the presence of a higher harmonic current component.
