Common active power filter circuit diagram with steady performance

Published:2011/5/9 22:16:00 Author:Nicole | Keyword: active power filter, steady performance | From:SeekIC

The circuit is as shown, the new frequency fo=3.4KHz, the notch frequency fo=9.5KHz, the quality factor Q=3.4. For high frequency filter, the transfer coefficient is 0.1, for band-pass filter, it is 1, for low frequency filter, it is 1, for notch filter, it is 10. foQ≤200KHz, when the output sine signal is within 10V, the maximum frequency is no more than 200KHz.
