摘要
文章就真空镀膜特种电源——非对称双极性脉冲开关电源的特殊要求、工作原理和研制设计要点作了详细论述;并就半桥式逆变电路在非对称双极性脉冲作用下,开关变压器铁芯偏磁与阶梯式趋向饱和现象进行了深入分析;同时,对偏磁现象的判断检测和补偿校正,提出了可行的解决办法。
This article particularly discussed the special requirements, working principle and key point of development design of the vacuum membrane plated special type power supply-asymmetrical ambipolar pulse switching-mode power supply; and analyzed the phenomenon of transformercore magnet polarizing and gradual tend to saturation of the semi-bridge system invert circuit under the asymmetrical ambipolar pulse; meanwhile, it brings out feasible solution for the judgment and check of magnet polarizing and compensate revising.
