Pulse Width Modulation and Current Control for DC Drives

In this chapter we will look at some basic drive implementations with a DC machine as discussed in Sect. 10.4 Our aim is to arrive at generic models of all major drive components (excluding the DC machine which has already been discussed) which we can then transpose to a PLECS type environment in the tutorials at the end of this chapter. A central topic of this chapter is the so-called pulse width modulation (PWM) which is used to realize uni-polar and bipolar voltage control of converters.
