Problem gelöst !!!!!!! Simulationszeit jetzt 10 min. statt 3 Stunden! Das Problem lag am IR2110 Model von H. Sennewald.
Ein Spezialist aus USA hat mir weitergeholfen. Siehe unten. Files siehe Anhang
Hello,
It seems that the IR2110 model is causing a lot of convergence problems. Perhaps it was only verified and optimized by the developer in the PSPICE software. Replacing it with a simple model solves the problem. But since we want to use some real world model, we can use the datasheet based model at LTspice simulation of H-bridge using IR2110.
I have modified the IR2110 which I have downloaded from that thread to be compatible with your circuit and attached here the working files. Good luck.
I have also seen from other threads to use the IR2110A model from the same manufacturer. You may also want to try it.
