The inverter module has been checked and ready for first tests.
Thanks to the wise instructions, the startup took place without any explosion or damage to the components.
Now I need to choose the capacitor on the secondary side of the transformer. With a capacity of 2uF, the waveform has visible oscillation, but the transformer is relatively quiet. at 20uF there is no visible oscillation, but the transformer becomes noisy - a hum can be heard and vibrations on toroid are felt, and the no-load current is slightly higher.
Do you have any suggestions for the capacitor?
Warpseed suggested setting the resonance to 1.5x the mains frequency, but this has been questioned by some on this forum.
