SoC implementation of an autonomous identification and control system for DC/DC power converters

The control system described in this work implements automatically a digital controller that achieves the highest possible cross-over frequency for the specified phase margin by applying a design method based on the measured frequency response of the DC/DC converter, identified by the system itself. The algorithms for the design, identification process and control of the converter are implemented on a SoC (System on Chip). The proposed algorithm to calculate the controller is described and the identification process and the designed compensator are validated through measurements on an actual converter.
