A study on the audible frequency area noise emanating from a pan when the IH cooker is fed by the power source including harmonics

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. In this paper, it is elucidated the influence on the pan’s vibration and the acoustic noise when the amplitude of the noise superimposed on the power supply is changed and it is clarified the lowest power supply noise level, which is corresponding to the recognizable audible noise.

Development of new high-performance induction heating systems using model predictive control1

“…Moreover, the controller ensures that ZVS operation is achieved, even during transient behaviour, by ensuring the proper current sign during the switching times, guaranteeing consequently a high-efficiency and reliable operation. As a conclusion, MPC has proved to be a useful tool for improving control systems of domestic IH systems subject to a wide variety of constraints [25].…”

Research on noise reduction of improving electromagnetic structure

“…on the noise contribution in the induction cooker heating process. The field of home appliances is currently the focus of most research on electromagnetic heating noise [3,4,5]. Related research in the industrial manufacturing sector, such as the development of crucible induction furnaces [6] and high-frequency induction furnaces [7], is currently only in the early stages.…”

A front-end PFC stage for improved performance of flexible induction heating appliances

“…In recent years, induction heating (IH) technology has become a reality in our homes [1][2][3][4][5]. This cooking technology has been developed in depth, and it has revolutionized the cooking way.…”

“…In order to achieve a cost-effective implementation, some multi-inverter structures have been proposed recently [8][9][10]. However, these structures add control restrictions and complicate the power control in the induction loads [2].…”
