I have a problem with programming in the attached file. I created this file in Prime 2 back in May 2013, and have been using it ever since to determine component values. In December, I also installed Prime 3. The programming loop of the file computes the period / frequency at which the output voltage equals a certain value Vgassing. I start the programming loop with the frequency 1Hz above resonance which will give me a huge output voltage. I then increment the frequency 0.1Hz until the output voltage drops to equal Vgassing. When I open the file in Prime 2, the file computes the period / frequency perfectly. If you change the input voltage Vac at the top of the page from 435V to 450V, you will see the frequency rise at the bottom of the page. When I open the file in Prime 3, it does not give me a value from the programming loop. If you change the input voltage Vac from 435V to 450V at the top of the page, the program just gives me a value of 0 for Ts. What do I have to do different for Prime 3 than I do for Prime 2 to make this programming loop work? Thanks.
