Abstract
This chapter introduces the basics of three-phase digital current controllers. Their practical implementation is digital, and it involves the PWM actuator and the feedback acquisition systems described in the previous chapter. The analysis and design of discrete-time current controllers rely on z-transform, and it takes into consideration all the feedback acquisition, computation, and PWM delays. In order to facilitate the introduction of some basic principles of the current control, this chapter does not take into account the discrete nature of the controller, nor does it consider the transport delays. Instead, the analysis is performed in s-domain.
