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 using current transformer. I only saw a resistor at output of the current transformer in book. So how can i find sense resistor in order to use for calculation ? Should i really need it ?
