The spice models it will attempt to debug a Ngspice is an incompatible spice model parameter.Īs ngspice parses through the circuit and reads One of the major causes of ‘time step too small’ in Here is a my own custom collection of spice models I was hoping that someone in the community could try any of the above and see if it works for them? I would love to know if I’m just doing something stupid. These are the components (gate drivers) I tried: Now, I imagine the questions here may be “what was the error”, but really, there was a variety of errors, from the spice files not loading in to the symbol editor (saying something about expected lines) through to errors like “doAnalyses: TRAN: Timestep too small ”. Then I built a basic test rig (ideal supplies, MOSFET H bridge powering a load) and worked through the list of gate drivers (with datasheets in hand), but not one worked. I have been to various websites (TI, Infineon, diode, to name a few), downloaded the spice model and created a footprint. However, I cant for the life of me get a gate driver to work. The circuit as a whole works really well (MPPT charging a “battery”, triangle wave gen etc). I am building a circuit which ultimately connects to a full bridge (H bridge) output. I am reasonably new to KiCad and this is my first post here, so apologies in advance if I offend anyone with my ignorance.
