Hi, I'm making an AC to AC matrix converter that has MOSFETs in series with the Source of one leading to the Drain of the next to allow voltage flow. However I'm encountering some problems in the MOSFET driver circuit as it is required to have a floating 0V for the MOSFET to work correctly. The Driver circuit contains a High side MOSFET driver (IRL2127 from Radionics) but I can't find this component in the library of 'LTSpice XVII'. Has anyone on here have experience in creating new components with the software or have any recommendations?
