Abstract
Embodiments for 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, and wherein 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.
Claims19
A multifilar inductor with at least three windings that are switchable comprising:
- a power assigned winding denoted as P1;
- a suppression component assigned winding denoted as B;
- a containment component assigned winding denoted as T;
- a respective temperature sensor associated with each P1, B, and T winding;
- a switching apparatus to switch assignments between the P1, B and T windings;
- and
- a capacitor bank coupled to the inductor, wherein the B winding suppresses back EMF generated by a pulse power generator and input to P1, the T winding contains field emitted EMF created by the pulse power, and further wherein 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.
A pulse power circuit comprising:
- an inductor configured as a pulsed power switched unipolar ungrounded component, and having one or more power windings (Pn), a containment winding (B), and a suppression winding (T);
- a set of input terminals coupled to input ends of the inductor windings;
- a set of output terminals coupled to output ends of the inductor windings;
- and
- a switching circuit having a first switch applying direct current (DC) pulse energy to a power winding P1, and configured to change an operating mode of the inductor based on a coupling of the input terminals to the output terminals, and wherein the B winding diminishes a reactive element consequential to a trailing edge of the power pulse delivered by the switch, and wherein the T winding abates the residual reactive element and subdues back Electromagnetic Force (EMF) energy emitted from the inductor, wherein the back EMF comprises an induced force that opposes the direction of current that is induced in the inductor, and wherein the pulse energy is input to a capacitor bank and converted to a constant current output 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.
A high-energy capacitive energy transform system, comprising:
- a multifilar inductor having a plurality of windings around a magnetic core including a power winding, a containment winding, and a suppression winding;
- a switching circuit having a first switch applying direct current (DC) pulse energy to the power winding, and configured to change an operating mode of the inductor based on a coupling of input terminals to output terminals of the inductor;
- a supervisory control unit disposed between a high voltage (HV) bank and a service bank (SV);
- and
- a suppression circuit coupled to the inductor and comprising a diode suppressing back Electromagnetic Force (EMF) generated by pulse power input to the power winding of the inductor, and a containment circuit comprising a wire winding the B winding and configured to contain field-emitted EMF created by the pulse power.
