工频变压器准降频应用的研究
摘要
目的 根据变压器铁芯磁化的工作机理
找出消除偏磁的方法.方法 利用开关器件关断时在绕组中产生的反电势
将该部分电能存储于消磁电容器之中.结果 利用消磁电容器放电时产生的反方向电流
抵消了铁芯中的剩磁.结论 最终使得变压器准降频使用成为可能.
Abstract
Aim\ An approach to eliminate magnetic bias is found according to the magnetization principle of transformer core. Methods\ By using the countervoltage
which is produced while the switch device is shut in the winding
the energy is stored in the degaussing capacitor. Results\ The remanence is offseted by using the countercurrent
which is produced during the discharge of the degaussing capacitor. Conclusion\ It is made possible to use the transformer with the quasifrequencyreducing.
