| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | We have so far proposed a noise-source equivalent-circuit model for predicting conducted noise from a DC-DC converter. The model is the black-box model that focuses only on the behavior of the conducted emissions on normal mode. Our previous studies validated the model by applying it to a Si-MOSFET buck converter. The application to the other types of converters still needs to be verified. In this study, we applied the model to a Si-MOSFET boost converter and GaN-HEMT buck converter. The model parameters were identified by using the measurement results according to the waveform decomposition method. The spectra predicted by using our model considering the switching fluctuation were compared with the measured spectra and it was found that they are in good agreement in terms of both the input and output ports in the same way as the Si-MOSFET buck converter. | |
