use of transformers. This article tells you what you need to know to add transformers to LTspice/SwitcherCAD III simulations. Draw Each Winding as an Inductor Figure 1 shows the basic technique. One simply draws each winding of the transformer as an inductor and couples the inductors with a SPICE directive called a K-statement (e.g.,

I wanted to simulate a pulse transformer in LTspice. It steps up the input 12 -12 pulses to 120V -145 pulses means it has some dc offset. How to correct it?

3phaseY : 3 Phase Transformer - Y. 3PHASE_D_Y : Three phase transformer - Delta wye Connection. XFRM_LIN/CT-PRI : Center Tapped Linear Transformer. XFRM_LIN/CT-PRI/SEC : Center Tapped Linear Transformer. XFRM_LIN/CT-SEC : Center Tapped Linear Transformer LTspice includes a library of basic models for a limited number of Coilcraft inductor models. These models are included in the standard inductor library and are updated periodically. Coilcraft also offers an easy to install and use advanced model library that can be downloaded from the LTspice library page linked to the right.

A transformer is just coupled inductors. Ideally, the power in the primary will be delivered to the secondary 100%. In real case, there is a reduction of power delivered to the secondary and this is the coupling loss. Coupling effectiveness is represented by a number less than unity to unity in LTSpice.

LTspice includes models for most of Linear Technology’s switch-mode DC/DC converters as well as a library of devices for general analog circuit simulation including op amps, compara-tors, linear regulators and discretes. LTspice/SwitcherCAD III is available LTspice/SwitcherCAD III is a powerful SPICE simulation tool with integrated schematic capture. Unlike many other free simulators, LTSpice is a general purpose tool and not limited.

About. LTspice IV is a free, high-performance, SPICE simulator software by Linear Technology which is widely used in the industry. The Wurth Electronics Midcom libraries contain LTspice models for over 650 of our power transformers, including designs for lighting and metering applications, PoE and PoE+, isolated DC/DC converters, flyback and offline transformers.

LTspice will faithfully model both ideal and real magnetic devices. However, caution is advised when first experimenting with unfamiliar concepts in inductors and transformers. Although it is possible to make a dedicated subcircuit for a specific transformer, LTspice preferred method is to define a separate inductor for each transformer winding and then couple them all together magnetically via a single Mutual Inductance (K) statement. LTspice/SwitcherCAD III is a powerful SPICE simulation tool with integrated schematic capture. Unlike many other free simulators, LTSpice is a general purpose tool and not limited.
