Digital Peak Current Mode Control Step-by-Step Design Guide


This article by Dr. Ali Shirsavar investigates the implementation of peak current mode control with slope compensation using a single Piccolo A from Texas Instruments.

The theory of operation, mathematical modeling and all relevant equations are presented along with a detailed step-by-step design procedure in both analog and digital domains. An example of a Buck converter is used to illustrate the process. The correct scaling factor which defines the crossover frequency is determined by measuring the frequency response of the complete system using the Bode 100.
