![]() save statements are included to improve precision yet minimize the number of measurements. Hint: Before stepping through the entire frequency range, test at a couple of frequencies (e.g., insert “.param Freq = 125K”) and look at V(A) and V(B) to ensure you have sufficient amplitude in your voltage source, and if possible, tighten up the frequency range to minimize simulation time. In this example, the simulation runs from 50kHz to 200kHz using five points per octave. step command to set the frequency range over which you want to perform the analysis. The difference between start and stop times in this case has been chosen as 25/freq so that the error from a non-integral number of switching cycles is small, since many cycles are included. Parameter t0 is the length of time required for the system to settle to steady state and also sets when the simulator starts saving data.
