What kind of relationship is there between signal generator block frequency and solution time step?
I designed the boost converter and used signal generator and comparator to get the signal for igbt. The frequency of the system is 25 kHz. When I set the solution time step as 50 us or 40, signal generator gives nothing. Signal that goes to comparator is 1 but in the output channel there is no frequency or any shape of signal. But when i set the solution step as 5us or 10, then I get the frequency shape that cycle between 0 and 1.
I dont understand why solution time step affects the signal generator block. How can I find the proper value of solution time step ? it also affects the output voltage of the converter.
