Now I am designing a power switching supply with the input: +/- 18V to +/- 28V, the outputs: four output +/-12V(isolated outputs, with individual Ground), the output power: 15W. I use the UC3845, but I am not sure the formulaeto calculate the values of electrical elements, especially the transfomer(I use the formulae from some books, but i am not sure they are suitable for my supply). Pls give me your advices and your experiences.
P/S: I am using the Ocard Pspice 9.2 to simulate the design, but my Pspice library dose not have library of the UC3845 (this element is in the Library of Capture only-the Regulators library). Pls send me the library for Pspice Simulation of the UC3845, UC3844 and so on...
Thanks in advanced!
