One method of evaluating a planar transformer would be to try simulating it in a software package such as LTspice. To get a decent 


These models are included in the standard inductor library and are updated periodically. 59: Ideal transformer in LTspice The simulation results are far closer to 

LTSpice will be used to account for these slight differences between real and ideal parts. 3.3Non-Ideal Resistors Reality is messy. Most lecture material covers electronics from an ideal point of view. Only in lab when using real 7) Basic Ideal Transformers and Their Parameters

  • The relationship between the Voltage and current are defined as equations below.
  • V P is the primary voltage.
  • V S is the secondary voltage.

    However, Spice does not allow a coupling coefficient of k=1. The ideal transformer can be simulated in Spice by making k close to one, and the inductors L1 and L2 very large, such that wL1 and wL2 is much larger than the resistors in series with the inductors. 2021-04-09 2019-01-23 2020-11-03 “Ideal” transformer models are usually used to make it as easy as possible for the developer and to reduce the computation time in LTspice. Only the inductance values for the primary and secondary are required here, as well as the coupling factor K (here in statement K1 Lp LS set to 1 = ideal). Then there's also the coupling factor of the transformer.

    LTspice will tell you that this transformer is impossible since it isn’t possible for L1 to be perfectly coupled to L2 and L2 perfectly coupled to L3 without some coupling between L1 and L3.

    The transformer is the most important component for the converter function. Therefore, a large part of the project was focused on selecting a suitable one. The result is LTSpice är till stor hjälp när de övriga komponenterna i  använt exempelvis ISSpice, LTSpice, NL5, MultiSim har några bra funktioner "The driver stage is transformer coupled to the power stage".
