Abstract：
The characteristic and performance of ripple feedback loop for output sub-harmonic suppression in BEPC main magnet power supply were studied, the limits of the loop effect are analysed and explained. The experimental studies on active filters to attenuate the power supply output ripple are described, the structure and design of the filter are also introduced in this paper.
