Solid State Relay Test

#1 · January 21, 2026, 7:07 pm

I tried the schematic of a solid state relay but the frequency of the wave across the lamp becomes 100Hz in Simulide 1.01 and 200Hz in simulide 2.0, while the waves in the oscilloscope appear to have the same frequency.

Hi, without the circuit file is difficult to test it.

To fix this you can increase the filter in freq meter and oscilloscope.
Does not fix the actual problem, but could be enough.

To actually fix the problem you need to synchronize wavegen and reactive steps.
For 1 us reactive step and sine wave 50 Hz, set "Quality" in WaveGen to 20000.

Same than this one:

In version 2.0.0 it is working ok for me, at least as it is right now.
Maybe I will port the solution from 2.0.0 (1.2.0), seems that is has been working.
