Progress in the development of a battery-based pulsed power system

Abstract

The development of compact, portable pulsedpower devices is of continuing interest, and recent technological developments such as high-energy-density capacitors, the emergence of SiC high-power devices, and the combined high power and energy density in electrochemical energy storage devices present an opportunity to use these technologies in applications of interest, such as high power lasers, railguns, and microwave systems. Several challenges exist when attempting to integrate these emerging devices into the development of a compact rep-rate pulsed-power system. These include but are not limited to the input power management, DC-DC converter efficiencies, and thermal management. This paper discusses the development of a battery-powered, rep-rate charger for a 60-kJ capacitor bank, and the desire to study the feasibility of such a system, especially the efficiency and reliability of the battery packs. This paper will discuss the system design and results from experiments to date.

Portable DC Supply Based on SiC Power Devices for High-Voltage Marx Generator

“…observed that most solutions use various types of transformer-based DC-DC converters [15][16][17][18][19][20][21][22]. In [15][16][17], a single active bridge was applied, while in some other works, a resonant converter can be found [19][20][21][22].…”

“…Taking into account these requirements, a portable DC power supply has been developed on the basis of silicon carbide (SiC) power device technology. The first step of the research was a literature review in the area of high-voltage power supplies and it was observed that most solutions use various types of transformer-based DC-DC converters [15][16][17][18][19][20][21][22]. In [15][16][17], a single active bridge was applied, while in some other works, a resonant converter can be found [19][20][21][22].…”

What is also interesting is a series connection of the DC-DC converters: a parallel-input series-output structure was discussed in [18], while a special topology was developed in [22], and in [19], a voltage multiplier was applied.…”

Battery Power Smoothing Control in a Marine Electric Power Plant Using Nonlinear Model Predictive Control

“…M/S Viking Queen will soon be retrofitted with batteries [6], while M/S Ampere is in operation and is driven by batteries only [7]. Using batteries on naval vessels to take care of pulse loads from the weapons system has been suggested [8], [9]. Batteries can also be used for emergency power, as demonstrated in [10].…”
