Zusammenfassung:	The utility model provides a filtering servo power supply. The circuit comprises an inductor L10, an inductor L20, an inductor L30, a high-power filter capacitor C1 and a high-power filter capacitor C2. One end of the inductor L10 is connected with a power supply inlet wire R of a three-phase power supply frequency converter; the other end of the inductor L10 is connected with a null line L1, oneend of the inductor L20 is connected with a power inlet line S of a three-phase power supply servo driver, the other end of the inductor L20 is connected with the null line L1 and a null line L2, andone end of the inductor L30 is connected with a power inlet line T of the three-phase power supply servo main shaft driver. The beneficial effects of the utility model are that firstly, three-phase ACvoltage is filtered by the inductor L10, the inductor L20 and the inductor L30, so that the used voltage is cleaner and more stable; and high-power filter capacitors are added between the zero line L1 and the zero line L3 and
