Double Pulse Test LTSpice simulation

Lucy

Hello,

Could you please help me solve the simulation errors when running the "DTP_Test_Stand_HB.asc".

Error messages are:

C:\Users\…\Wolfspeed_SPICE_Models\Modules\LTspice\Models\WS_HalfBridge.lib(167): Expected ")" here.
.param LmflagQ1 = {if(LcsiQ1+0.5,7,6}

C:\Users\…\Wolfspeed_SPICE_Models\Modules\LTspice\Models\WS_HalfBridge.lib(168): Expected ")" here.
.param LmflagQ2 = {if(LcsiQ2+0.5,7,6}

…

Attached screenshot to show the error messages.

I followed all the instructions in "SPICE Module Model User Guide.pdf" and the video tutorial Simulate Power Module Performance with LTspice | Wolfspeed.

I have search paths set up to \Wolfspeed_SPICE_Models\Modules\LTSpice\Models.

I checked the previous discussion LTSpice simulation errors — Wolfspeed Power Applications Forum, and changed the solver from normal to alternate. My LTSpice is Version(x64): 24.1.9.

Thanks,

Lucy LU

Hi there,

Are you using the latest version of the models on our website? This issue should be fixed with the latest copy.

Also - we will be releasing a new version of the model library to our website soon that will fix all of the convergence errors on the normal solver and some improvements to accuracy, so keep an eye out for that.

Thanks,
