5kJ capacitor bank fired at 12kVDC / 3.5kJ charge

Third experiment with the bank of 35 electrolytic capacitors connected in series. Results are better than theoretical estimate, which was 6000 A limited by ESR, so getting just over 7000 A is good, but the result is still a little … Continue reading

5kJ capacitor bank fired at 2kJ charge

Second charge experiment with the bank of 35 electrolytic capacitors connected in series. The bank did however not get charged to more than 50% of its maximum holding charge, properly due to too weak power supply. More results will follow … Continue reading
