Abstract
A system comprising a high voltage (HV) bank section using capacitors arranged into two banks, a multifilar inductor coupling the HV bank to a service voltage (SV) bank section and load through a charging circuit charging the SV bank from a more fully charged bank until the charging bank is depleted, and a switch switching, from the depleted bank to the other bank of bank to charge the SV bank. The charging circuit then charging the depleted bank by a power supply as the other HV bank charges the SV bank. A supervisory controller controls the switch to repeat switching and charging between the two banks for a defined period. The capacitors may be supercapacitors having a capacitance on the order of 1 to 10 MegaJoules.
