Background/Objectives: An integrated circuit enabled the manufacturing of small electronic appliances. However, these circuits were vulnerable to unwanted emissions from various power sources. We present an investigation study on EMI (Electromagnetic Interference) of a power converter circuit for solar energy systems. Methods/Statistical Analysis: We use an artificial network to estimate and measure the unintentional emissions on power lines. The components normally act as an isolation circuit. A DC-DC power converter circuit is designed and manufactured. The simulation results of unintentional emissions are presented. To reduce the emissions, a revised circuit with capacitors and ground posts is fabricated. Test methods and conditions used here are explained. Findings: The emissions for conduction and radiation were measured in the EMI test facility based on the standardized testing procedures. The results show the unwanted emissions from the circuit are diminished tremendously due to the suggested EMI reduction techniques. Improvements/ Applications: In this study, the measured EMI emission values for a power converter circuit are presented. The results proposed here can be usefully applied on designing power converter modules.
