WebFeb 16, 2024 · Resistor value was calculated using R_damp = (Q* (Sqrt (L/C))) With Q = 1, R_damp = 4.76 ohm. This can set SMPS always in Over current protection state. Increasing the resistance makes the filter under damped. One solution I figured out was to place the R_damp in series with C_damp = (10*C). In physics and engineering, the quality factor or Q factor is a dimensionless parameter that describes how underdamped an oscillator or resonator is. It is defined as the ratio of the initial energy stored in the resonator to the energy lost in one radian of the cycle of oscillation. Q factor is alternatively defined as the … See more The Q factor is a parameter that describes the resonance behavior of an underdamped harmonic oscillator (resonator). Sinusoidally driven resonators having higher Q factors resonate with greater amplitudes (at the resonant … See more The Q factor determines the qualitative behavior of simple damped oscillators. (For mathematical details about these systems and their behavior see harmonic oscillator See more For an electrically resonant system, the Q factor represents the effect of electrical resistance and, for electromechanical resonators such as quartz crystals, mechanical friction.
