WebDec 18, 2024 · A wide-bandwidth current-controller is required for the fast charging and discharging of applications containing super capacitors. To accomplish this, peak current mode is generally used due to the speed of its response characteristics. On the other hand, peak current mode control must be provided with a slope compensation function to … WebJan 20, 2014 · 34. Jan 20, 2014. #1. Hi. I am confused at slope compensation for UC3825. In application note of UC3825, normal sense resistor has been used but i need to use current transformer because of high primary current. In formula in application note, sense resistor has been used for slope compensation but there is no sense resistor in case of …
WebFigure 3. DCDC Boost Converter under Digital PCMC when current sense is implemented on the LS, and slope compensation is applied directly on the sensed inductor current. For a DC‐DC Boost Converter, the HS current sense approach is usually preferred, since transients in the sensed WebCurrent-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. The current feedback loop has two right-half-plane zeros in the transfer function that lead to instability. The PWM switch model, developed by Dr. Vorpérian, works perfectly well ...
