Closed-Loop Digital PWM Control using a Popular Power Electronics Platform

This paper describes how a buck converter implemented on a power pole circuit board (a popular platform for study of DC-DC converters) can be digitally controlled using a Texas Instruments Piccolo kit. The control algorithm is implemented using block diagrams in Simulink, and automatically generated code is targeted onto the Piccolo processor. The power pole circuit board and the Piccolo kit are shown to provide an effective platform for the study of digital control algorithms. Various converters can be assembled quickly on the power pole board, and corresponding control algorithms can be rapidly deployed and tested on the Piccolo kit.
