====== LTspice ======

We use LTspice to simulate the circuits.\\
It can be downloaded for free: https://www.analog.com/en/design-center/design-tools-and-calculators/ltspice-simulator.html

===== OSS library =====

To make it easy all necessary models are summarized in the OSS.lib\\
Just copy it into the project folder and add the following command in LTspice (press "S"):
  .include OSS.lib

History OOS.lib
  * Version 0.1
  * Stand: 02.01.2022

Included models
  * Thyyristor MCR706A Source: ON Semiconductor (Now: Littelfuse)
  * Diode UF4007 Source: http://ltwiki.org/index.php?title=Standard.dio

===== Ignition coil =====

To create an ignition coil, you create a transformator. Add to inductivities (press L) L1 and L2 and then create a directive (press S): 
  K1 L1 L2 0.7
This creates the transformator K1 with L1 and L2. And the last number is the efficiency. 1.0 is an ideal transformator with no loss and 0.7 is a good approximation for a standard ignition coil.

===== Note =====

LTSpice is not case-sensitive, so for the unit prefix "Mega" you need to write 1000k or meg, because m/M stands for milli.

===== Simulation =====

This is a first version of a LTspice simulation. It shows the CDI at the Vape 70-3.\\
The red curve is the voltage of the high voltage coil V1 and the green curve is the voltage of C3.{{ ::1102-demo-ltspice-vscdi3.png?600 |}}

Its not perfect yet but it works.
