Because the circuit needs current overload protect, a double loop strategy , with current feedback of filterinductance as inner loop and output voltage as outer loop, is studied.
根据需要电路电流过流保护的特点，重点介绍了滤波电感电流反馈做内环，输出电压做外环的双环控制策略。

Its main idea is to use controllable reactor to adjust inductance continuously, so to keep filter working around resonance point.
其核心思想是利用可控电抗器连续调节电感量从而保持滤波器在谐振点附近工作。

Based on the design of the core inductance of the power filter, this paper presents analysis on the characteristics of the amorphous core and the microcrystalline core.
