Design and Implementation of a DSP Based Digital Controller for a DC-DC Converter

The design and digital signal processor (DSP) based implementation of a digital controller are presented for the dc-dc converter. Starting with a dc-dc buck converter and a given set of performance specifications, a digital PID controller is implemented in TMS320F2812 DSP. All the necessary DSP hardware or software techniques and algorithms required to implement the controller are discussed in detail. The steady state and dynamic response performance of the controller is presented in order to demonstrate the effectiveness of the design.
