This is the second time I'm trying to simulate a SEPIC converter today. First I went with [LT3959][1], but after hours of trying to make it work, I assumed there is something wrong with the component and it would be easier to choose another component and everything would work. The second time i went with [LT8364][2] and again I did everything as the datasheet said, placed realistic components (parasitic C,L,R) but again I can't make it to work. I'm using the newest version of LTspice. (LTspice XVII (x64), May 4 2018 **The problem that occurs is that the output voltage is 0V.** [![enter image description here][3]][3] This is my schematic: [![enter image description here][4]][4] Vin and Vout: [![enter image description here][5]][5] Can anyone help me? Should I instal older version of LTspice? *.asc file: [link][6] [1]: http://www.analog.com/media/en/technical-documentation/data-sheets/3959fa.pdf [2]: http://www.analog.com/media/en/technical-documentation/data-sheets/8364f.pdf [3]: https://i.sstatic.net/kyjQS.png [4]: https://i.sstatic.net/g3C8t.png [5]: https://i.sstatic.net/kfZAG.png [6]: https://drive.google.com/open?id=1SxleEaWlSjyyVKHol32b03OllJxvW7Hk
