POWER CONVERSION SYSTEM HAVING A HARMONIC DISTORTION LIMITER

摘要

An electrical power conversion system having a harmonic distortion limiter. The power conversion system includes a power converter having a power input, a power output, a current measurement output signal, and a control signal input. The system further includes a controller having a voltage control subsystem arranged to measure a voltage present at the power output of the power converter and generate a corresponding current reference signal. A current control subsystem of the controller is arranged to receive the current reference signal and the current measurement output signal and generate a corresponding modulation command signal, the modulation command signal of the controller being electrically coupled to the control signal input of the power converter. The power converter is responsive to the modulation command signal to limit harmonic distortion at the power output of the power converter.
