Current Control of Generalized Load

Abstract

The ability to control the currents in an electrical machine is essential for manipulating its mechanical torque and magnetic flux, as will become apparent in Chap. 4. This chapter considers current control techniques for single- and three-phase voltage source converters which are connected to a generalized load as introduced in the previous chapter. The use of this type of load is instructive given that it reflects the electrical behavior of most electrical machines which are in use today. Consequently, the current control techniques discussed in this chapter may be applied for electrical machines discussed in this book. Attention has been given to the use of voltage source converters because these are widely used in low- and medium-power drive applications. However, for high power applications, current source converters are still deployed. These converters are considered outside the scope of this book.
