electromagnetic compatibility of dc/dc power supply. Firstly an expression of Logistic map is derived, which can generated chaotic sequences with controllable amplitudes. Then a chaotic sequence is applied to perturbs reference current parameter in hysteresis current control scheme. Power spectrum of inductance current is spread and electromagnetic interference on switching frequency and its harmonic frequency is reduced. Simulation results show that the new scheme can improve electromagnetic compatibility of the dc/dc converter.

good concept to use spread to power device to reduce EMC problem ,this could cook out a lot of idea ----sigmadelta ,spread spectrum ......作者: dad30520 時間: 2008-12-8 10:25 PM
想看看謝謝你ㄉ檔案...沌提高dcdc變換器的EMC性能.最近在找報告所以界參考依下......
