| 摘 要： | 针对单向激磁的Buck电路磁芯得不到充分利用的问题，提出一种采用双向激磁方式增加Buck电路磁芯中磁感应强度动态变化范围的方法，讨论了驱动信号交替方法电路的电压增益、占空比和电感临界值的计算公式，开关频率3．3kHz的试验结果为激磁电流由0．33A降到0．11A。

| Abstract: | Aiming at the problem that the core in unidirectional magnetization Buck circuit can not fully be utilized,a method to enlarge the dynamic variation range of magnetic induction intensity in Buck circuit was proposed,in which a two-direction(ZD) magnetic exciting mode is used.In addition,the voltage proliferation and ratio of the circuit which is driven alternately and computing formula of critical inductance were discussed.And some experimental results at on-off frequency of 3.3 kHz shows that magnetic electrical currents decrease from 0.33 A to 0.11 A. |
