    在對全橋開關型變換器電路工作原理分析的基礎上，建立了全橋開關型變換器主要元器件的電磁干擾參數模型，利用cadence軟體對其pcb主要印製導線進行了建模分析和寄生參數的提取，得到了全橋開關型變換器傳導干擾的共模、差模噪聲電流等效電路模型以及噪聲模擬模型，並運用saber軟體進行了傳導性干擾噪聲的模擬研究，分析了主要寄生參數對電路噪聲的影響。
  3. Comparing to inducing - magnetic mode with 50hz alternating current, we can use lower frequency alternating current to induce the magnetic so that it can eliminate the noise at 50hz frequency and weaken the noise whose phase lags signal 90 ? greatly. comparing to inducing - magnetic mode using rectangle - wave current as the signal, using low frequency to induce magnetic can eliminate ( weaken ) the differential coefficient noise. thirdly, it eliminates or weakens all different noise by designing the circuitry effectively in the transforming signal part

    相對於50hz交流勵磁，這種勵磁方法可以採用更低的頻率來對微流量的磁路進行勵磁，一方面可以完全消除工頻干擾，另一方面可以極大地減小正交干擾；相對于方波勵磁，這種勵磁方法相當于多值方波勵磁，有利於消除或減少方波法勵磁所帶來的微分干擾。
