Outline of Final Research Achievements |
Direct Current Circuit Breaker (DCCB) is considered to be indispensable to develop the DC power feeding system. For this purpose, current commutation method using outer capacitor charge is proposed. By using EDLC dc power supply developed for high voltage and high current experiments, DCCB using proposed method has good ability at 180V, 22A experiments within the suppressed capacitor voltage.
