WebAug 20, 2024 · To set a transformer in LTpsice, place two inductances L1, L2 and then, define the Mutual Coupling (K) through a Spice directive. The phase dots will automatically show up once you define the directive. An ideal transformer has mutual coupling equal to one, while real ones present lower values, as it is later explained.

WebHowever, the SN650x models should work in LTSpice. It's possible the inductors are not behaving as a transformer normally would since they look like coupled inductors. Please attempt to use the P-SPICE for TI SN6505B reference models linked here, if possible. Otherwise, please analyze the SN6505 model in a configuration as shown in the test ... WebMar 7, 2024 · LTSpice calculates the turns ratio of a transformer with SQRT (Lp/Ls). This is however only true if both windings have the same geometry. I have an air-core transformer with an Lp of 10μH, an Ls of 30μH, a turns ratio of 10 (and a coupling coefficient of 0.5). How can I simulate this? WebIn contrast, the capacitors used in a charge pump do not produce any more EMI than a typical digital output. They can be easily routed in short traces to reduce antenna area and capacitive coupling, resulting in lower EMI. Table 1 compares inductor-based switching regulator and switched capacitor inverting topologies. hatch alternatives
