A Study on the Audible Frequency Area Noise Emanating from a Pan when the IH Cooker is Fed by the Power Source Including Power Source Noise

Abstract

　This paper describes the effect of power supply noise on the acoustic noise and pan vibration when making use of the IH (Induction Heating) cooker. Recently, due to the spread of power electronics device, noise superimposed on the AC power supply is a problem. It has been reported that the acoustic noise provides discomfort feeling when using the IH cooker. Other studies have concluded that the vibration of a pan due to the induction heating is the noise source. So, we started our study on the noise from a pan when making use the IH cooker. Furthermore, we clarify the influence of power source noise on the acoustic noise and pan’s vibration. We made an experiment to clarify this influence. As a result, we clarified that power source noise has influenced acoustic noise and pan’s vibration.
