7.3 Compact Pulsed Power

Oral

In this contribution we present the first implementation of a solid-state impedance-matched Marx generator (IMG). Our application - transient plasma for environmental applications - requires fast (several ns rise time), high-voltage pulses with flexible pulse duration (10-100’s of nanoseconds) and amplitude (up to several tens of kV). The IMG topology was introduced in 2017 by researchers from...

7.3 Compact Pulsed Power

Oral

The Center for Physical and Power Electronics has developed a nanodielectric material (MU100) to reduce the size of ultra-high voltage (UHV) pulsed power capacitors. In the discharge regime of interest the dielectric constant of the material is 200. The UHV dielectric, 3.4 cm diameter, 2 cm thick substrates with voltage ratings on the order of 260 kV, were assembled into a series stack of 4...

7.3 Compact Pulsed Power

Oral

The reliable detection of special nuclear materials continues to be a primary goal of national security programs conducted by the NNSA Defense Nuclear Nonproliferation organization. While these programs are diverse, many share a core need for a small, robust pulsed neutron generator. This project addresses this need by deploying a recently developed portable dense plasma focus (DPF) neutron...

1160. Low Energy Laser Triggering at 1535 nm

7.3 Compact Pulsed Power

Oral

The use of lasers to initiate the closure of high-power gas switches was initially explored soon after the development of suitable high power pulsed lasers in the 1960’s. The low jitter, excellent triggering range, and galvanic isolation provided by laser triggering has been extensively exploited in the triggering of megavolt switches in large pulsed power machines. However, the lasers and...

550. Microsecond Fast, 100 kV Modular Pulse Charger

7.3 Compact Pulsed Power

Oral

A pulse charger module was designed and tested for use in scaled experiments. Each pulse charger module is powered with a 12 V Lithium-ion battery and set to charge a 1 nF capacitor up to 100 kV in less than 10 µs. This is achieved by initially charging a 1.5 µF capacitor to 5 kV. Using a thyristor switch, this capacitor will then discharge into two transformers paralleled on the primary side....

919. New Marx based generator using IGBTs for adjustable quasi-rectangular pulses

7.3 Compact Pulsed Power

Oral

The use of semiconductor switches in pulsed power field experienced big progress in the last decade. The offered intriguing characteristics, combining compactness, controllability and simplicity of control, help to build generators with controllability level which was not possible to achieve with classical switches.
This work is about a new architecture of solid-state modular Marx generator...
