Good Afternoon Everyone,
I am currently working on building a high current lithium-ion battery charger and was wondering if there would be anyway to reduce ripple voltage from a full-wave rectifier without adding additional capacitance. At the current specs of 108V and 14 Amps, the circuit requires a ridiculous amount of capacitance (~2.3F) to smooth the ripple. This will of course be extremely expensive to implement. This DC voltage will then be stepped down by a buck converter. Does anyone know of a good trick to remove the ripple voltage without large amounts of capacitance?
Thanks for the help!
