磁损
    1. Core loss model under sinusoidal waveform excitationThe parallel resistance model is proposed in this dissertation.
    1、正弦波信号激励下的磁损模型
    So the nonlinear core loss model can be represented by a linear model.
    这样就把非线性的磁损问题转化为线性模型来加以处理。
    2. Core loss model under rectangular waveform excitationThe dissertation makes a research on the core loss model under rectangular waveform excitation.
    2、矩形波信号激励下的磁损模型
    A ratio named KD is introduced and defined as the ratio of core loss under rectangular waveform excitation to that of under sinusoidal waveform excitation supposed both of which are under the same frequency and the same flux density.
    论文还研究了矩形波激励下的磁损模型,引入一个比例系数K_D,定义为相同频率、相同磁感应强度下矩形波激励磁损与正弦波激励磁损的比值。
    3. Core loss model under the influence of DC bias magnetic fieldThe dissertation also makes a research on the influence of DC bias magnetic field to the core loss.
    3、直流偏置磁场影响下的磁损模型
    Similarly, a ratio named KB is introduced, defined as the ratioof core loss of sinusoidal waveform excitation with DC bias to that of without DC bias, supposed that both under the same frequency and flux density.
    论文同时研究了直流偏置磁场对磁损的影响问题。 同样引入比例系数K_B,定义为相同频率、相同磁感应强度条件下含直流分量的正弦波磁场产生磁损与纯正弦波磁场磁损之比。
    It is guessed that the ratio of core loss of DC/DC converter filter inductor to core loss under sinusoidal waveform excitation under the same frequency and same AC flux density is the product ofKo and Kg.
    作者猜想这种情况下磁损的数值和相同频率、相同磁感应强度纯正弦波激励产生磁损之比等于K_D和K_B的乘积。
    Combined with the inductor core loss models under sine wave excitation, the influences of DC bias magnetic field and rectangular wave excitation on core loss are studied.
    结合正弦波激励下的电感磁损模型,研究了直流偏置磁场以及矩形波激励这两种情况对磁损的影响。
