Ripple (electrical)
OverviewCapacitor vs choke input filtersVoltage rippleFiltering in power suppliesRipple currentFrequency-domain rippleSee also
A capacitor input filter (in which the first component is a shunt capacitor) and choke input filter (which has a series choke as the first component) can both reduce ripple, but have opposing effects on voltage and current, and the choice between them depends on the characteristics of the load. Capacitor input filters have poor voltage regulation, so are preferred for use in circuits with stable lo…
