A pulsed power generator, Pawn, has been assembled at the Naval Research Laboratory. It employees inductive energy storage and opening switch power conditioning techniques with high energy density capacitors as the primary energy store. The energy stored in the capacitor bank is transferred to a vacuum inductor in "'15 ps. Wire fuses provide the first stage of pulse compression. Futiher power c...

A pulsed power supply with a compact and low-cost electric-double-layer-capacitor (EDLC) is developed for generating magnetic fields long pulse duration of few seconds. The system demonstrated in three experimental setups using 10.7 F- or 50 F-EDLC capacitor bank. By the bank 27 mm wide-bore magnet, field peak strength 24.3 T ∼1 s generated. profiles are reproduced theoretical calculations taki...

The losses at distribution level contribute a major portion of power system losses. Proper sizes of shunt capacitors in unbalanced radial distribution systems (URDS) can reduce some portion of this loss and can improve the voltage profile of the feeder section. Most conventional optimization techniques are in capable to solve this hard combinatorial problem with set of operating conditions wher...

This paper presents Genetic Algorithm based approach to shunt capacitor placement in distribution systems specially IEEE 30 bus system for optimal configuration with the multi-objective placement problem for enhancement of distribution system reliability. IEEE 30 bus is well defined and load flow is evaluated to observe the line losses, p.f. and voltage profile. Placement of shunt capacitor ban...

Plasma diagnostics were carried out in a theta-pinch device to investigate the applicability for plasma– material interaction under fusion-like conditions. A series of triple probe diagnostics show that the plasma is sustained for approximately 80 ls at each pulse, with 3.0 (10) m 3 plasma density and up to 40 eV electron temperature when a 32 lF main capacitor is discharged at 20 kV. In order ...

A novel capacitor bank is proposed to implement a wide-band CMOS voltage-controlled oscillator(V CO) with linearized tuning characteristics. Taking advantage of the Ohms law, the tuning voltage is replaced by the product of the current and resistance, which provides one more freedom degree for tuning than the conventional V CO. This novel voltage equivalent capacitance array(V ECA) is clearly d...
