Abstract

본 발명은 시스템으로 공급되는 파워의 레벨을 검출하는 경우, 파워에 포함되는 리플 성분을 제거하여 파워제어를 정확하게 수행한다. 이를 위하여 먼저 수신되는 정현파 파워 신호를 제곱 승산하여 제1 제곱신호를 발생하고, 또한 정현파 파워 신호를 90도 위상 쉬프트 시킨 후 제곱 승산하여 제2 제곱신호를 발생한다. 이후 제1 제곱신호와 제2 제곱신호를 가산하면, 정현파 신호에 의한 리플성분이 제거되고 파워 레벨 성분만 검출되어 출력된다.In the present invention, when detecting the level of power supplied to the system, power control is accurately performed by removing the ripple component included in the power. To this end, a first square signal is first generated by multiplying the received sinusoidal power signal by a square, and the second square signal is generated by multiplying the sinusoidal power signal by 90 degrees after the phase shift. Thereafter, when the first square signal and the second square signal are added, the ripple component due to the sine wave signal is removed, and only the power level component is detected and output.

그러므로 시스템에서 필수적인 파워의 제어를 정확하게 할 수 있다.Therefore, it is possible to precisely control the power necessary for the system.
