Abstract
The presence of increasingly sophisticated and innovative cooking utensils such as induction cookers has changed the way of cooking by providing a high level of efficiency. Induction cookers are also a breakthrough in reducing carbon emissions and making them an important choice in energy conservation efforts. The use of induction stoves in the community still faces several obstacles such as relatively high prices, significant power consumption, and the need for special cooking containers. In addition, the development of induction stove technology can produce electromagnetic emissions in the form of conduction emissions. Conducted emission is electromagnetic interference caused by electronic devices through conductors which can be interpreted as noise currents that propagate on the conduction path and have the potential to interfere with other electronic equipment through voltage sources. In the same power grid, conducted emissions caused by induction stoves can also interfere with data signals using Power Line Carrier (PLC) at a frequency of 30-500 kHz. This study aims to understand and identify patterns of electromagnetic wave emission, namely conduction emissions produced by induction stoves. The main focus is on conducted emissions, which can affect the performance of such electronic devices. The results of research related to the characteristics of the conducted emission value of this induction stove are expected so that this household device is safer and more comfortable to use by the community and can provide a reference for the further development of induction stove technology. The test method was carried out on 4 (four) brands of induction stoves C, A, M and P under various operating conditions and cooking modes both individually and simultaneously in the frequency range of 9 KHz-30 MHz through Electromagnetic Compatibility (EMC) testing. The measured parameter is a Quasi Peak (QP) value, in accordance with CISPR standard 14.1:2020. Based on measurements in the frequency range of 9 kHz-30 MHz, individual conditions were obtained that some of the induction stoves used in this study were above the threshold values required in CISPR 14.1:2020. Based on measurements with the condition that the induction stove is operated simultaneously, the level of conducted emission decreases and there is a disturbance at a new frequency beyond the disturbance frequency at individual conditions.
