| Abstract(in English) | A reduction design of conducted disturbance from power converter circuits is becoming more important as electronic devices are requiring much more power efficiency. Conducted disturbance must meet domestic and international regulations. In this paper, a linear equivalent circuit model on the basis of a EMC macro-model of IC/LSI, LECCS model, is investigated to predict the conducted disturbance of power converter circuits. The dual-port LISN (DP-LISN) constructed to provide the model is also reported. In the study, an commercial table-top induction heater is used as the equipment under test. Conducted disturbance voltages were measured with 10 different load pairs of the DP-LISN. Model parameters were then determined by the least square method with the conducted disturbance voltages measured. We simulated conducted disturbance voltages for evaluation by use of the linear equivalent circuit model as an evaluation of the model. As comparing simulated and measured disturbance voltages, the spectrum of the conducted disturbance voltages agreed with each other in their envelopes. |
