The proposed solution uses a discrete-time controller with digital slope compensation implemented using only a single-chip microcontroller. Detailed frequency response measurements are taken using the OMICRON Lab Bode 100 to confirm the stability of the converter.
Loop Measurement of Digital Peak Current Mode Control
This article by Dr. Michael Hallworth and Dr. Ali Shirsavar investigates a microcontroller-based peak current mode control of a Buck converter.
