    respected everyone
    i am doing my project on "High Step-Up DC-DC Converter with Coupled-Inductor and Voltage-Doubler Circuits" . the rating is 24v input, 200v output, 250w output power. The calculated value of induct-or is 48u Haney. I start doing it with simple conventional type which gives output around 52(theorytical 65v).
    but when i add coupled induct-or and voltage doubler in this circuit then insted of
    increase output, the output decrease to 45 voltage. what happen i canno't understand. Please help me .
    Here is the schamatics on pspice.

    I think you need to attach a circuit for *.gif or *.png file, because some other members may not using the pspice, but they still can help you.
