  • The objective of this book is to acquaint the reader with explosive driven pulsed power devices, theory and applications. This includes those devices that convert the chemical energy stored in high explosives into electrical energy and that use shock waves generated by the explosives to release the energy stored in ferromagnetic or ferroelectric materials in the form of electrical energy. The reader might well ask why one should use explosive driven pulsed power for any application, since it is inherently single shot in nature.

  • Positioning systems in general have their most basic form, and also the most complex, in the human being. The brain serves as the summing network that accepts the command for a desired motion or position, the musculatory system serves as the power source or prime mover to cause motion to take place, and the sensory system, such as the eyes, determines the present position. In general, these three things—the brain, the muscles, and the eyes—are analogues to the three basic parts of any positioning system....

  • Power electronics is the technology of processing and controlling the flow of electric energy by supplying voltages and currents in a form that is optimally suited to the end-user’s requirements [1].Atypical block diagram is given in Figure 1.1 [2]. The input power can be either AC and DC sources. A general example is one in which the AC input power is from the electric utility. The output power to the load can be either AC and DC voltages. The power processor in the block diagram is usually called a converter. Conversion technologies are used to construct converters.

  • Today’s wind energy industry is at a crossroads. Global economic instability has threatened or eliminated many financial incentives that have been important to the development of specific markets. Such economic sponsorship of energy generation is not unique to renewables; fossil based sources are also subsidized in many different countries. However, for a technology like wind energy whose markets are still developing, incentives can be critical for industry growth.
