Abstract :
A novel technique for building active filters using switched-capacitor (SC) circuits is proposed. The principle of operation, methods of control, and analysis and design of a typical SC filter are presented. To assess its effectiveness, the technique is used to control input current harmonics in a phase-controlled converter. It is shown that by using a single filter a wide range of harmonics can be controlled
