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, the electronic device of the induction heating method according to an embodiment of the present invention, a noise printed circuit board for reducing the noise of the AC power output from the input power supply unit, receives AC power from the noise printed circuit board, and controls the driving of the compressor A main printed circuit board and a noise printed circuit board and an induction heating printed circuit board that receives power from at least one of the main printed circuit boards and controls an induction heating operation of the working coil, wherein the main printed circuit board includes a noise printed circuit An auxiliary power supply unit for rectifying and outputting AC power supplied from the substrate as direct current power, and first and second switching elements and a second switching element for driving a compressor by receiving direct current power output from the auxiliary power supply unit and performing a first switching operation. It includes a compressor driving unit having a capacitor connected in parallel to both ends of the switching element.
