WebJul 24, 2024 · So if the square wave (switching waveform) was 12 volts p-p then the fundamental would be reduced by 40 dB to 120 mV p-p and the harmonics reduced even more. If the switching frequency is 100 times the LC natural frequency then the 12 volts p-p is attenuated by 80 dB to 1.2 mV p-p. WebA reasonable design procedure is to let the reactance of the output capacitor contribute no more than 1/3 of the total peak-to-peak output voltage ripple (V P-P ), yielding: (28) Using V OUT = 12V, I OUT = 1A, V IN = 5V, f = 40kHz and V P-P =200mV, This leaves 67% of the ripple attributable to ESR, giving: (29)
