Patent number: 11631988Abstract: A system comprising a high voltage (HV) bank section using energy storage devices arranged into one or more banks, an inductive device 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 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 discharging and charging between the two banks for a defined period. The energy storage devices may be supercapacitors capable of storing energy on the order of 1 to 10 MegaJoules, and the inductive device may be a high-inductance, toroidal multifilar inductor.Type: GrantFiled: December 18, 2021Date of Patent: April 18, 2023Assignee: Richard H.

Publication number: 20230088782Abstract: Embodiments of a multifilar inductor with at least three windings that are switchable, having a power assigned winding denoted as P1, a suppression assigned winding denoted as B, a containment assigned winding denoted as T, a switching apparatus to switch assignments between the P1, B and T windings; and a capacitor bank, wherein B suppresses the back EMF generated by a pulse power, T contains field emitted EMF generated by the pulse power. The input pulse power input is converted to a constant current output into the capacitor bank such that its time duration is extended by the combination of the inductor windings plus the capacitor bank to thereby minimize the peak inductance below the inductor's saturation point.Type: ApplicationFiled: November 28, 2022Publication date: March 23, 2023Inventor: Brian Elfman

Publication number: 20050218971Abstract: A self-calibrating an auto-tracking voltage regulation method and system is provided that includes a superior voltage reference and a less stable operating voltage reference. The superior voltage reference may be a thermal resistor heated zener (TRZ) that is turned on only during a relatively low duty cycle sampling period. An error signal generator compares the superior voltage reference and a feedback voltage to generate an error signal based thereon. An error correction unit combines the error correction signal and the operating voltage reference to produce a calibrated output voltage that has a greater voltage stability than the operating voltage reference.Type: ApplicationFiled: March 30, 2004Publication date: October 6, 2005Applicant: B.P.
