Abstract:
A control system for a harmonic neutralized frequency changer. The control system includes a processor, a narrow band harmonic controller and a fundamental current controller. The narrow band harmonic controller is communicably connected to the processor and is configured to reduce a positive sequence component, a negative sequence component and a zero sequence component of a harmonic generated by a cycloconverter of the harmonic neutralized frequency changer. The fundamental current controller is communicably connected to the processor and is configured to reduce a fundamental frequency component of current flowing in a neutralization inverter of the harmonic neutralized frequency changer.
