A method for obtaining the capacitance and inductance of double-tuned AC power filter is discussed in the paper. The method calculates the resonant frequency of the series resonant circuit according to the preset resonant frequency, the first and the second resonance frequencies of parallel resonant circuit; and calculates the first inductor, the first capacitor, the second inductor and the second capacitor of double-tuned AC power filter ac-cording to the resonant frequency of the parallel resonant circuit and the resonant frequency, first and second resonant frequencies of the series circuit. Experimental results showed that this method does not require solution of multiple or quartic equations but merely needs to list concise expression based on a quadratic relationship between roots and coefficients to quickly and accurately calculate the parameters of double-tuned filters.
