Size Capacitor

04/23/2009 1:47 PM

my circuit is switched capacitor DC/Dc bidirectional converter. that high voltage side (battery voltage) is 250V and low voltage side (Ultra-capacitor voltage) is 180V and initial low voltage 150V. the capacitor is between these 2 side voltages in parallel and battery and Ulta capacitor with inductance (in series) get connect to capacitor .I don't know how calculate size and value capacitor?

Maxwell Technologies has some nice downloadable tools on their website for sizing.
