MODELLING, ANALYSIS AND COMPENSATION OF THE CURRENT-MODE CONVERTER
As current-mode conversion increases in popularity, several peculiarities associated with fixed-frequency, peak-current detecting schemes have surfaced These include instability above 50% duty cycle, a tendency towards subharmonic oscillation, non-ideal loop response, and an increased sensitivity to noise. This paper will attempt to show that the performance of any current-mode converter can be improved and at the same time all of the above problems reduced or eliminated by adding a fixed amount of “slope compensation” to the sensed current waveform。
