Electromagnetic safety of an induction heating power supply
Switched mode power conversion systems have been widely used in recent years because of their high efficiency, small size and weight. But they are rich sources of electromagnetic interference (EMI) due to the square pulses, which are full of high frequency components, used for the switching action. On the other hand electromagnetic compatability (EMC) has become more important in recent years due to the international standards developed for the emissions from different types of electronic devices. Standard setting organizations have established limits lo, exposures from various devices including both commercial and military, requirements, and also to prefect public health. In our department, a load resonant power supply of 10kW/200kHz tons realized for induction heating purpose. in this study, the EMC concept is examined for this induction heating power supply unit.
