PURPOSE:To shorten the time of a transition state by selecting solutions of damping oscillation functions so that one of the capacitance value and the inductance value of a resonance filter may be twice as high as the input fundamental frequency and the other may be four or more even-number times as high as the input fundamental frequency. CONSTITUTION:In a filter used in an inverter circuit, etc., the resonance frequency of resonance circuits L00 and C01 connected in series to loads L05 and R05 is caused to agree with the input fundamental frequency, and reactance L00 and capacitance C03 which resonate to the third harmonic wave and capacitance C04 for bias are connected in parallel with loads. Values of L00, C03 and C04 which resonate to the third harmonic wave are so selected that one of two damping oscillation functions obtained by solving a status equation may be approximately two times as high as the fundamental frequency and the other may be approximately four or more even-number times as high as the fundamental frequency. |
