Abstract

A system and method for controlling a power converter includes a digital-to-analog converter (DAC) and ramp generator for generating a reference current command. The DAC is configured to decrement (or increment) to a next state after a fixed number of clock pulses have occurred. The reference current command controls an output of the power converter. Means are provided for delaying an output of the DAC for a number of clock pulses less than the fixed number to increase a resolution of the DAC.
