Webon how to create one with a spice command. First, create two inductors L1 and L2 to be the two windings. Press ‘T’ to get the “enter text” dialog and check the “SPICE Directive” … 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. Figure 1.

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. 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?
WebThe syntax for a mutual inductanceis as follows: Kname Inductor1 Inductor2 value_of_K In which K is the value of the coupling coefficient that determine the mutal inductance: M=K.sqrt(L1xL2). An example of a complete SPICE file for the circuit given below follows.

The solid rectangle is the "engine" for the variable inductor. It is to be used together with B1, that is B1 + F1 + L1 form an inductor, whose "interface" to the world is B1, inside the dotted rectangle.
