| Abstract: | The performances of ceramic capacitors,polymer film capacitors and electrolytic capacitors are briefly introduced and applications of these kinds of capacitors in large voltage,high frequency power converters are compared.In this paper,the advantage of electrolytic capacitors which are used to restrain yawp and high exponent wave pollution produced by the switch power and to improve energy conversion efficiency in the high pass power train circuits is emphasized.In addition,the methods of reducing equivalent series resistance(ESR)and low temperature impedance are put forward to improve the performance and reliability of the output filter sections. |
