It is always the frequency which causes X L and X C to cancel each other out, X L + X C = 0)X L = X C)! 0L = 1! 0C)!2 0 = 1 LC)! 0 = r 1 LC (6) where ! 0 = 2ˇf 0, the resonant angular frequency. You must be able to calculate the resonant frequency for arbitrary RLC circuits.

The impedance seen by the source Vs is 1 1 ZRjL jC RjL C ω ω ω ω =++ ⎛⎞ =+⎜⎟− ⎝⎠ (1.3) Which at 0 1 LC ωω== becomes equal toR. • Therefore at the resonant frequency the impedance seen by the source is purely resistive.
NCP1342 - Quasi-Resonant Flyback Controller, High Frequency
www.onsemi.comQuasi-Resonant Flyback Controller, High Frequency NCP1342 The NCP1342 is a highly integrated quasi−resonant flyback controller suitable for designing high−performance off−line power converters. With an integrated active X2 capacitor discharge feature, the NCP1342 can enable no−load power consumption below 30 mW.
