In this chapter, laboratory experiments for digital control of switched DC-DC power converters are presented. The converter is implemented by using operational amplifiers. The operational amplifiers are used for modeling the mathematical equation developed from the converter. The controller is programmed using a microcontroller-based board. This methodology allows and easy way to implement and solve the problems related to digital control, and the reinforcement of theoretical concepts. A buck converter with a voltage loop has been chosen to show these issues. The microcontroller is the F28335 from Texas Instruments. Finally, results are presented.
