EMI AN INDUCTION HEATING TYPE ELECTRONIC DEVICE HAVING ENHANCED EMI REDUCTION PERFORMANCE

摘要

The present invention relates to an induction heating type electronic device with improved EMI reduction performance. In addition, according to an embodiment of the present invention, the induction heating type electronic device comprises: a noise printed circuit board for reducing noise of alternating current power outputted from an input power supply unit; a main printed circuit board for receiving the alternating current power from the noise printed circuit board and controlling driving of a compressor; and an induction heating printed circuit board for receiving power from at least one of the noise printed circuit board and the main printed circuit board, and controlling an induction heating operation of a working coil, wherein the main printed circuit board includes an auxiliary power supply unit for rectifying the alternating current power received from the noise printed circuit board into direct current power, and outputting the rectified direct current power, and a compressor driving unit for receiving the direct current power outputted from the auxiliary power supply unit to drive the compressor, and having first and second switching elements for performing a first switching operation and a capacitor connected in parallel to both ends of the second switching element.
