Abstract:
A system for controlling load current in a voltage converter includes a current normalization module that receives a first measurement corresponding to the load current, receives a second measurement corresponding to an inductor current, and matches a first gain of the first measurement corresponding to the load current to a second gain of the second measurement corresponding to the inductor current to generate a normalized load current. A feed-forward generation module receives the normalized load current from the current normalization module and generates a load current feed-forward (LCFF) signal based on the normalized load current. A duty cycle generation module generates a duty cycle used to control the voltage converter based on a commanded output voltage of the voltage converter and the LCFF signal.
