Hello everyone,

I am simulating a Switched Capacitor DC-DC buck converter. I would like to measure the output voltage ripple. But the output voltage signal is not periodic signal as it it has no unique pattern. Does anyone know how to calculate the voltage ripples for non-periodic signal ??

Thanks,
Dima Kilani
 

If this ripple is not periodic, you can use a modern oscilloscope that has a recording capability.The oscilloscope will record this non-periodic waveform in a long term time slot and you will able to measure peak-to-peak ( or avarage,rms etc).
 

First try to define what the "ripple" is. Ripple usually is defined for pulsed signals as deviation from the "straight" pulse top or bottom.
For non-periodic signals, what is their form? What the "ripple" should be?
