Abstract
본 발명은 인버터 장치가 출력하는 구동신호의 출력 주파수 변동에 따른 소음의 증감현상 및 음색의 변화를 감소시키고, 전동기의 동작특성을 향상시킬 수 있도록 하는 것으로서 종래에는 인버티 장치로 전동기를 구동시킬 경우에 구동 주파수에 따라 캐리어 주파수가 서로 상이하고, 이 캐리어 주파수에 따라 소음 주파수의 대역이 결정되므로 발생되는 소음의 음색이 변화되었으며, 또한 인버터 장치를 구성하고 있는 스위칭 소자의 스위칭 주파수의 한계 및 마이콤의 용량 한계에 의하여 최대 캐리어 주파수의 한계가 결정되므로 캐리어 주파수가 작은 영역에서 구동되는 운전 주파수가 발생하게 되어 소음 진동이 크게 발생하였다.The present invention is to reduce the increase and decrease of the noise and the change in the tone according to the output frequency change of the drive signal output from the inverter device, and to improve the operating characteristics of the motor. The carrier frequencies are different from each other according to the driving frequency, and the tone of the noise is changed because the band of the noise frequency is determined according to the carrier frequency, and the limit of the switching frequency of the switching element constituting the inverter device and the Since the limit of the maximum carrier frequency is determined by the capacity limit, an operating frequency driven in a region having a small carrier frequency is generated, resulting in a large noise vibration.
본 발명은 실내기 지령 주파수와 흡력 주파수의 크기를 비교하고, 비교결과에 따라 출력주파수를 증감시켜 각각의 운전 주파수에서 최적의 캐리어 주파수로 운전하므로 소음의 발생을 줄일 수 있고, 거의 일정한 캐리어 주파수로 운전하여 음색이 일정함은 물론 전동기의 특성을 향상시켜 운전할 수 있다.The present invention compares the magnitude of the indoor unit command frequency and the absorption frequency, and increases or decreases the output frequency according to the comparison result, thereby operating at the optimum carrier frequency at each operating frequency, thereby reducing the occurrence of noise and operating at a substantially constant carrier frequency. As a result, the sound quality is not only constant, but also the characteristics of the motor can be improved.
