Power supplies high voltage direct current

Commercially available regulated high-voltage direct current (d.c.) power supplies are of three types a bench top rack-mount unit with multiple features, a compact modular-type unit with... 

The previous chapters address various aspects of quantitative bond graph-based FDI and system mode identification for systems represented by a hybrid model. This chapter illustrates applications of the presented methods by means of a number of small case studies. The examples chosen are widely used switched power electronic systems. Various kinds of electronic power converters, e.g. buck- or boost converters, or DC to AC converters are used in a variety of applications such as DC power supplies for electronic equipment, battery chargers, motor drives, or high voltage direct current transmission line systems [1]. 

The power supply for the electrolysis cell is usually supplied as a high voltage AC current. It must be rectified to direct current and reduced to the required voltage for the cell. 

Monopolar electrodes have a direct electrical connection with an external power supply. This requires the distribution of current over the total area of one monopolar electrode, collecting the current from the other monopolar electrode for conduction to the next cell through intercell busbars. Monopolar cells operate at low voltages, and may require high amperages. Industrial circuits of cells may consist of one hundred or more monopolar cells in series. Monopolar electrodes are used in some membrane chlor-alkali cells (Figs. 4 and 5), fluorine cells (Fig. 6), and in metal electrowinning cells (Fig. 7). 

A calutron consists essentially of an intense source of uranium ions, a way to accelerate the ions to high energy within a vacuum system, and a way to collect the uranium-235 and uranium-238 ions after they have moved in separate arcs between the poles of a very large electromagnet. The components at the heart of the system are ion sources, collectors, and high-voltage, regulated direct-current power supplies (Lore, 1973 London, 1961 USDoE, 1980). 

Dc-dc converters are the basic building blocks of modern high-frequency switching power supplies. As their name suggests, they convert an available dc (direct current) input voltage rail Yin, to another more desirable or usable dc output voltage level Vo. Ac-dc...
