sawtooth_psim_dll

This sawtooth wave generator was tested in PSIM 2022.3.0.60 64bits and its intended to overrun the issue with the element "Saw-tooth voltage source (grounded)".

The sawtooth-wave voltage generator doesn't work properly when the frequency is about 1/10 of the frequency of the simulation.

As shown in figure 1, the signal vtri_cg (blue) not always get to value of 1. figure 1

The FFT from both signals shows in figure 2 the correct frequency at 25kHz. figure 2
