Wurth Electronics Midcom Inc. Releases LTspice Transformer Library

Wurth Electronics Midcom Inc. announces the release of the LTspice Transformer Library. The library provides LTspice models for products including the flyback transformer product group, PoE and PoE+ products, offline power solutions, isolated DC-DC converters, and power supply solutions for lighting and metering applications.

Wurth Electronics Midcom offers two libraries: the Standard Library and the Basic Library. The Basic Library is similar to other LTspice transformer models present in the industry. It can also be imported into and converted for use in other SPICE programs. The Standard Library includes all of the parameters of the Basic Library models, and additionally model parasitics and saturation effects, making them accurate, while at the same time quickly simulating.

The symbols in both libraries show the windings, pinout and phase dot for easy reference. One highlighted feature of the Standard Library is the user's ability to choose one of two models (either Linear or Saturation) for any product. The Linear model includes parasitics and runs 25% faster than the Saturation model, which runs slightly slower, but has the advantage of modeling saturation effects as well as parasitics.

Product Marketing Manager at Wurth Electronics Midcom, Dean Huumala, states: "Usable transformer SPICE Models for switching power supplies have always been an industry challenge. The Wurth Electronics Midcom LTspice Transformer Library provides transformer models that give realistic results while simulating very quickly."
