With the advancement of high voltage silicon carbide insulated- gate bipolar transistors (IGBTs) and metal oxide semiconductor field effect transistors (MOSFETs) with voltage hold-off ratings of 10kV and above and current ratings of 5A and above, possible uses for continuous power applications are being explored. Switching high voltage and high current typically requires a costly test circuit...

In an era when vehicle weight is very important to mission success, non-traditional technology must be developed to provide protection without adding parasitic weight to a vehicle, such as added by heavy armor packages. Electromagnetic Armor (EMA) is one possible technology that may accomplish the goal of achieving lighter weight with equal or greater protection levels. EMA is a system that...

Runaway electron beams play the dominant role in the process of nanosecond pulse discharges, which cannot be fully explained by traditional discharge theories and attracted continuous attentions. In this paper, a new collection device for runaway electrons in nanosecond pulse discharges based on faraday cup was investigated. A VPG-30-200 pulse generator was used to excite discharges and...

With the next generation of semiconductor materials in development, significant strides in the Size, Weight, and Power (SWaP) characteristics of power conversion systems are presently underway. In particular, much of the improvement in Wide-Bandgap (WBG) and Ultra-Wide-Bandgap (UWBG) device efficiencies and power densities are realized through higher voltage, higher frequency, and higher...

The reliable running of the transformers are extremely important for the electric system. However, during operating the transformers will inevitably suffers the various impacts, such as short-circuit current and mechanical vibrate. It will lead to permanent deformation, for example warping, shifting and bulge of the windings, within a power transformer. If cannot be detected on time, the...

For the new linear collider at the European spallation source (ESS) in Lund, 2.88MW long pulse modulators with pulsed output voltages of 115kV and pulse lengths in the range of milliseconds are required.
For generating many pulses, a long pulse modulator based on a modular series parallel resonant converter (SPRC) topology [1] has been developed. This converter is operated at high switching...

Electrical and electronic equipment used in aerospace applications must be designed to operate over a wide range of environmental conditions that include variations in pressure, temperature, and humidity. Electrical power systems for advanced aircraft utilize voltages well above the traditional levels of 12 to 42 Vdc and 115/200 Vac, 400 Hz. Current airborne systems can contain 270 Vdc, and...
