| Abstract |
While supercapacitors offer high power density, high cycling capability and mechanical robustness, voltage and current ripple from downstream PWM converters can result in their overcharging or heating resulting in their lifetime reduction. This paper discusses how a simple novel design scheme of using a very low value series inductance significantly increases capacitor lifetime. |
