How to Choose a Bypass Capacitor Size
This means large capacitors take a long time on charging and discharging while small capacitors can quickly do this to act like an open circuit, not allowing the current to pass (high impedance). Therefore, a large value capacitor can be used when low impedance is desired. Calculating Bypass Capacitor Size With PSpice
batteries
According to this answer, you''d want to use capacitors rated for 400-450V, since per unit volume they give you most energy stored. You''ll want to charge them up to 95% of the rated operating voltage, and discharge them down to 50-100V. The lower discharge voltage depends on how good a switching converter you can put together to efficiently convert the …
