Abstract
펄스폭 변조제어형의 인버터용 제어장치에 관한 것으로, 상기 제어장치는 출력 신호를 발생시키기 위해 인버터 출력용 기준치를 발생시키기 위한 기준발생기와 상기 인버터의 출력전압 또는 전류를 검출하기 위한 검출기를 포함하고, 상기 제어장치는 소정주파수의 코사인 및 사인성분의 순시값을 발생시키기 위해, 기준치와 출력신호간의 편차를 발생시키기 위한 비교기와 그의 입력신호로써 상기 출력 신호와 편차중 하나를 수신하도록 접속된 고조파 제거회로를 더 포함하고, 또한 상기 제어장치는 상기 편차와 상기 기준치 및 변조율을 발생시키기 위한 순시값을 수신하도록 접속된 변조율 발생회로와 상기 변조율에 의한 펄스폭 변조신호를 발생시키기 위한 게이트제어회로를 포함하고 있다.A control apparatus for an inverter of a pulse width modulation control type, the control apparatus includes a reference generator for generating a reference value for inverter output to generate an output signal, and a detector for detecting an output voltage or current of the inverter. The control apparatus includes a comparator for generating a deviation between the reference value and the output signal and a harmonic rejection circuit connected to receive one of the output signal and the deviation as its input signal, to generate an instantaneous value of the cosine and sine components of a predetermined frequency. The control apparatus further comprises a modulation rate generating circuit connected to receive the deviation and the instantaneous value for generating the reference value and the modulation rate and a gate control circuit for generating a pulse width modulation signal according to the modulation rate. It is included.
상기 펄스폭 변조신호는 상기 인버터의 출력 제어용 인버터로 인가된다.The pulse width modulated signal is applied to an output control inverter of the inverter.
