Switches in Circuits

  • R. S. Ramshaw


This chapter is concerned with the description and analysis of circuits that employ switches to modulate power in the load. In a circuit a configuration of switches that modulates or conditions power is called a converter. Thyristors are the switches that are shown in the figures of converters throughout this chapter. Any other appropriate semiconductor switch could be substituted, since, in the most part, the switch is treated as being ideal in this chapter and the analysis is, therefore, the same. The following chapters describe the different kinds of switches, the details of their characteristics and their areas of application.
