Abstract
본 발명은 정류기의 제어 장치에 관한 것으로서, 특히 전원측 컨버터와 부하측 컨버터 사이의 완충기 역할을 하는 직류 링크 캐패시터의 용량을 줄이기 위한 부하 전류 관측자를 이용한 정류기의 직류링크 전압 제어 장치 및 펄스폭변조 정류기의 전향 제어 장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control device of a rectifier, and more particularly, to a DC link voltage control device and a pulse width modulated rectifier of a rectifier using a load current observer for reducing the capacity of a DC link capacitor serving as a buffer between a power supply converter and a load side converter. It relates to a control device.
미지의 외란으로 간주한 부하 전류 관측자, 부하 전류 관측자를 이용한 전압 제어부, 전압 제어부의 출력을 소정의 전류이득 특성으로 제어하는 전류 제어부, 전류 제어부 출력을 펄스폭 변조하여 출력하는 전압 변조부, 변압 변조부의 펄스폭 변조된 게이팅 신호에 따라서 스위칭되는 전원 링크부, 전원 링크부에 전원을 공급하는 전원부, 부하측의 전원 변동을 줄이기 위한 완충부 및 미지의 부하를 포함하여, 미지의 부하전류를 추정하여 전원측에서 미리 보상해 줌으로써 전원측 컨버터와 부하측 컨버터 사이의 완충기 역할을 하는 캐패시터의 용량을 대폭 줄일수 있는 것을 특징으로 한다.Load current observer regarded as unknown disturbance, voltage controller using load current observer, current controller for controlling output of voltage controller with predetermined current gain characteristics, voltage modulator for pulse width modulating and outputting current controller output, transformer modulation The power supply side estimates an unknown load current, including a power link unit switched according to a negative pulse width modulated gating signal, a power supply unit supplying power to the power link unit, a buffer unit for reducing power fluctuations on the load side, and an unknown load. By compensating in advance, the capacity of the capacitor, which acts as a buffer between the power-side converter and the load-side converter, can be greatly reduced.
