In this study, an investigation study on EMC(Electromagnetic Compatibility) is presented for power converter circuit. A DC-DC power converter circuit using LT3652 chip is designed and fabricated. The simulation results using ANSYS SIwave for far field radiation and unwanted emissions are presented. To minimize the unwanted emissions, we design a optimized circuit by using capacitors and ground posts. The conducted and radiation emissions are measured in the EMC test chamber based on standardized testing procedures of CISPR 22. The measured EMI emission values for a power converter circuit are presented and compared with the original circuit. The results show that the unwanted emissions from the circuit are tremendously diminished due to the applied EMI reduction techniques. The results proposed here can be usefully applied on designing power converter modules.
