Publication number: 20160173053Abstract: A power shunt EMI filter is electrically connected to a power feeding line of a main functional IC and other loads. The main functional IC driven by a power source supplied by the power feeding line generates an output voltage and an output current which are individually involved with an output voltage interference and an output current interference, and a phase difference exits there-in-between. A reference providing circuit generates a reference signal according to the output voltage interference and/or the output current interference. At least one adjust filtering circuit calculates eigenvalues of the output voltage interference and/or the output current interference according to the reference signal, such that the phase difference and amplitudes of the interferences are zero. Thus, an output voltage signal and current signal the load receives are DC signal without interferences.Type: ApplicationFiled: March 9, 2015Publication date: June 16, 2016Inventor: TUNG-YANG CHEN

Publication number: 20160173052Abstract: A power EMI suppression filter is connected to a power feeding line of a main functional IC and other loads. The main functional IC driven by a power source supplied by the power feeding line generates an output voltage and current which are individually involved with an output voltage interference and output current interference, and a phase difference exits there-in-between. A reference providing circuit generates a first reference signal according to the output voltage interference and/or the output current interference. A primary filtering circuit calculates eigenvalues of the output voltage interference and/or the output current interference according to the first reference signal to generate a second reference signal. A secondary filtering circuit calculates eigenvalues again based on the second signal so the phase difference and amplitudes of the interferences are zero. Thus, an output voltage and current signal the load receives are DC signal without interferences.Type: ApplicationFiled: March 9, 2015Publication date: June 16, 2016Inventor: TUNG-YANG CHEN
