Abstract This paper introduces the resonant condition of LC parallel resonant circuit and the resonant condition under ideal condition. Through the combination of calculation and simulation, the analysis of the actual resonant circuit, which makes the waveform sine is affected, the distortion of the parameters. Combined with the full-response resonant circuit with sinusoidal excitation source of the same frequency, the parameters that affect the optimal resonant state when the circuit is at a fixed resonant frequency are derived. Finally, the above theory is verified by experiment, and the characteristics of LC parallel resonant circuit are obtained.
