High Power Active Filter using LC Tuned Filter.
IEEJ Transactions on Industry Applications, 1992 Usually, to eliminate the harmonics of transmission lines, LC tuned filters are employed to let bypass these harmonic components. But the elimination ability is limited by its damping resistance. Therefore, active filters composed of high frequency PWM converters are desirable.
