PRBS비트에 따른 준 랜덤 캐리어 변조기법의 소음 스펙트럼
Acoustic Noise Spectra of the Pseudo-Random Carrier Modulation Technique According to the Different PRBS Bits
초록
This paper describes the acoustic noise spectra of the pseudo-random carrier modulation technique according to the different PRBS(Pseudo Random Binary Sequence) bits. To confirm the validity of the proposed method, a 130v three-phase 5-level inverter motor drives was implemented. The harmonics spectra broadening effect of pseudo random carrier and the acoustic noise radiated from the inverter drives were discussed and verified according to the different bits of shift resister operating as PRBS.
