The present invention relates to technology which blocks noise of an audible frequency band generated when an inverter is operated. The present invention provides a noise removing method of an inverter for vehicles and a system thereof. The noise removing method of an inverter for vehicles detects switching frequency information of the inverter if the inverter is operated to operate a drive motor, and generates a reduction frequency for offsetting the audible frequency to remove the noise caused by the audible frequency when the audible frequency is detected from the switching frequency.

    본 발명은 인버터 작동시 발생하는 가청 주파수 대역의 소음을 차단하는 기술에 관한 것으로, 본 발명에서는, 구동모터의 작동을 위해 인버터를 작동하는 경우, 인버터의 스위칭 주파수 정보를 검출하고; 상기 스위칭 주파수 중 가청 주파수 검출시, 상기 가청 주파수를 상쇄하기 위한 리덕션 주파수를 발생시켜 가청 주파수에 의한 소음을 제거하는 것을 특징으로 하는 차량용 인버터의 소음 제거방법 및 시스템이 소개된다.
