In LTSpice there is no "turns" or "60k ohms". Those are just comments. It is all about inductance. Inside the transformer there is 180pF. They assume you will add 5pF with a transistor. L1,L2,L3=three inductors. "k l1 l2 l3 1" makes the three a transformer. "1" connects them together very well. 0.98 might be better. Note I added a Rser to V1.
Se hela listan på detail-infomation.com Sampled Data Analysis Using LTSpice. What is this page about? Sampled-data systems are interesting if you are considering closing your control loops via a digital controller or compensator of some sort. A starting point is to model the system using an analogue simulation in LTSpice and then translate it into a digital form.

LTSpice transformer mystery: M. Hamed: 1/9/15 10:22 PM: Any idea why the circuit below (also at the posted link) behaves like this? The load impedance at the secondary is 100K.
Apr 5, 2018 Hello to all, is it possible to simulate a transformer (floating) without connection to ground with ltspice? in this example
Rather than clog it up, I decided to make a quick tutorial and it can be made sticky if people find it useful, otherwise it'll just sink to the bottom of the list and rot, if it's no good. Three phase transformer.

LTspice includes a library of basic models for a limited number of Coilcraft inductor models. These models are included in the standard inductor library and are updated periodically. Coilcraft also offers an easy to install and use advanced model library that can be downloaded from the LTspice library page linked to the right. 2019-04-29

I am using SPICE engine (LTSpice) to model a center tapped transformer and then drive its primary side (center tapped) using MOS switches as follows: What I am expecting to see at the output terminals is the amplified square-wave given at the input.

Your inductance ratio is 50/.15 = 333.3, so the turns ratio is the square root of that, or 18.26. This makes your output voltage 18.26 × 12V = 219V. Depending on their size, real transformers would have values about 1/10 to 1/100 of what you used, but for modeling purposes, it isn't all that critical.
They perform critical function in providing an isolation barrier, enabling high step-down or step-up ratios and accommodating multiple or inverting outputs. Transformers and coupled inductors are key components in many switching regulator designs to include flyback, forward and SEPIC converters. They perform crit A center-tapped rectifier is a type of full-wave rectifier in which a center-tapped transformer is used. It converts both halves of each cycle of an alternating signal into a pulsating signal. A rectifier is an electrical device that converts alternating current or voltage (AC), into direct current or direct voltage (dc). LTSpice transformer is set in terms of primary and secondary inductances. The relation between inductance and turns ratio is For instance, the primary winding voltage is 120Vrms (169.71 peak), to get around 53V peak on secondary winding, the inductance ratio should be For a 400uhenry primary inductance, the secondary inductance would be LTspice IV: Using Transformers Transformers and coupled inductors are key components in many switching regulator designs to include flyback, forward and SEPIC converters.
