Be sure to minimize simulation problems by including reasonably realistic parasitic resistances (both series and parallel) directly into each inductor, whether used individually or as part of a transformer.Ī good learning and reference resource is the Transformer and Inductor Design Handbook Chapter 17, Winding Capacitance and Leakage Inductance 4th Edition by Colonel William. However, caution is advised when first experimenting with unfamiliar concepts in inductors and transformers. LTspice will faithfully model both ideal and real magnetic devices. 1.10 Now how do I plot a B-H curve to see the Chan model's hysteresis-saturation curves?ĭo you wish to study the behavior of transformers and inductors and explore their mysteries? LTspice is the ideal learning tool for this purpose.1.9 Chan Transformer (saturating magnetizing inductance with hysteresis - limited energy storage).1.8 Linear Transformer (linear magnetizing inductance - potentially unlimited energy storage).1.7 DC to DC Transformer (no magnetizing inductance - no energy storage).Is there some way to just enter a turns count for all the windings? 1.6 Okay, but calculating winding inductances is tedious.1.5 How about transformer saturation effects? Can LTspice model those?.

1.4 I want to model leakage inductance - how should I do that?.1.3 I've created an ideal transformer so it should work at all frequencies, even including DC, right?.1.2 How do I make a transformer in LTspice?.
