Abstract

본 발명은 인버터 제어 알고리즘에 관한 것으로, 일반적으로 사용되고 있는 인버터 제어 알고리즘은 정현파에 가깝게 펄스쪽 변조 신호를 발생시키는데 지나치게 분해능을 크게하여 8비트 마이콤으로서는 감당하기 어려운 데이타 처리 속도와, 메모리의 크기에 제한을 받게 된다. 또한 제2도와 같은 파형의 생성을 위해서는 각 상에 대하여 각각 3가지의 f(H)를 인가해야 하므로 처리속도의 문제가 발생하게 된다.The present invention relates to an inverter control algorithm. In general, the inverter control algorithm which is generally used generates pulse-side modulated signals close to a sine wave, so that the resolution is too large to limit the data processing speed and the memory size, which are difficult to handle with an 8-bit microcomputer. Will receive. In addition, in order to generate the waveform as shown in FIG.

이에 따라 본 발명은 상기와 같은 종래 회로의 결함을 감안하여 전체 한 주기의 정현파 데이타를 U, V, W상으로 구분하여 메모리에 저장하고 정현파의 1/3 주기와 2상의 데이타만을 저장하고 위상과 상만을 변경함으로써 8비트 마이콤으로 충분히 효과를 내도록 창안된 것이다.Accordingly, the present invention divides the sinusoidal data of one cycle into U, V, and W phases and stores it in a memory, and stores only 1/3 cycles of sinusoidal data and two phases of data. By changing the phase only, it was designed to make an effect with 8 bit microcomputer.
