Until now, environmental problem has become more and more serious, and acoustic noise is one of environmental<br/>
pollutions. For many years, ANC(Active Noise Control) has been made to reduce this noise.<br/>
In this paper, active silencer using switching method is studied. This silencer is composed of single-phase full bridge inverter to drive cancelling loudspeaker. The inverter is controlled to reduce noise by ramp comparison control method. At the vacuum cleaner, noise control with FFCS(Feed-Forward Control Structure) is applied and geometric arrangement is replaced to avoid unstability of FFCS.
