WebModulating reference current with a compensating ramp is a traditional method to stabilize the operation of the peak current-mode controlled DC/DC boost converter. In this paper, this method is applied to a PFC boost converter for gaining the stable operation target. WebA dominant pole represents the current-source effect, and a double pole at half the switching frequency shows the subharmonic oscillation. Current-mode control can become unstable even at duty cycles below 50%, and a compensating ramp must be added for some converters that are limited to 50% duty cycle. perma chink stains

WebJun 8, 2024 · During the converter on-time, the switch or inductor current rises to Iout + ILp-p/2. During the off-time, the current decreases to Iout – Ilp-p/2 and the output current is the average current. For peak current limit, the switch current is compared to the current limit value during the on-time. WebIt received a huge boost in popularity in the form of the world’s first current-mode control (CMC) chip, the Flyback controller UC1842 from Unitrode. In CMC, there is in effect a (fast-acting) “inner” current loop along with the “outer” (slower) “voltage loop” which carries out the output regulation. See the note on ramp
