Lpo is the primary inductance measured with the secondary inductance open unconnected.Īssuming to obtain k = 0.99, the leakage inductance will beĬalculating in 50mOhm the resistance to the primary, our dual winding transformer model can be this:ġ. Lps is the primary inductance measured with the secondary inductance shorted To calculate the leakage inductance, assuming a primary inductance L1 of 90.4uH, we have before calculate the coupling factor K Write tha name of model on the Value property Report the number of turns of primary and secondary, for example L1_TURNS=29 and L2_TURNS=4 Write the name of implementation and the path to the library Place the component, select it, mouse dx button/Edit Properties Now let’s open a new project and pickup the XFRM_NONLINEAR model from the BREAKOUT library:
