Introduction to TINA TI 0 - Explanation of TINA, download and installation

The free version of the program is already very comprehensive. You can find it as follows (recommended is link 1!):

1. TINA TI Download on this wiki (login via university account)
2. in the ILIAS course
3. Download (a bit cumbersome) via the TI page

Manual

An English manual can be found at here in the wiki.
A German manual is only available for the full version.

Exercises

Please install TINA TI.
Here are some tips:

• For „User Name“ and „Company Name“ you can enter pseudonyms (Hinz&Kunz, HHN).
• Select European (DIN) at „Select schematic symbol set you to want to use“.
• All file paths should fit as recommended.

The following introduction is based on videos in German. For the English introduction please refer to the first lecture available in ILIAS.
Alternatively, a nice introduction is also available on yoututbe from Professor Fiore.

Introduction to TINA TI 1 - Structure of TINA TI, first circuitry

Learning Objectives

By the end of this section, you will be able to:

1. be familiar with the various component bars in TINA TI,
2. insert and rotate components and their descriptions,
3. edit component values,
4. draw connections.

Tasks

1. Rebuild the circuit from the video in TINA TI.
2. Change the following additional values:
   1. Output value of the voltage source: $10 V$
   2. Size of resistor R1: $20k$
   3. Size of resistor R2: $30k$

Introduction to TINA TI 2 - Output of values and debugging

Learning Objectives

By the end of this section, you will be able to:

1. perform the „Electrical Rule Check“ and use it for debugging,
2. measure output values such as voltages and currents,
3. use multimeters in TINA TI to measure voltages and currents,
4. insert current measuring points correctly,

Tasks

1. Rebuild the circuit from the video in TINA TI.
2. Instead of the Current Arrow, use the Ammeter and instead of the Voltmeter, use the Voltage Pin.
   Are there any differences when you use them?
3. Imagine you want to build a small circuit with 3 light-emitting diodes and wonder how much the voltage of the two 1.5V batteries will drop.
   1. Build the simplified parallel circuit 1 (see picture).
      The internal resistance of the battery should be 500mOhm (property „Internal Resistance“).
      1. What voltage/current is measured?
      2. How large is the current through one strand?
   2. Optional: To do this, reconstruct the parallel circuit 2 (see picture). The internal resistance of the battery should be maintained.
      1. What voltage/current is measured?
      2. What is the current through one strand?

Solution:Battery voltage 2.97V, battery current for variant 1: 74.07mA, battery current for variant 2: 67.76mA

Introduction to TINA TI 3 - Even more errors and many diagrams

Learning Objectives

By the end of this section, you will be able to:

1. correct the most common errors in the simulation yourself,
2. display time sequences of signals,
3. work with the cursor in diagrams, separate curves, and insert a legend,
4. create and evaluate curves over temperature and other variables,
5. create a structured simulation with a title.

You can find the template file under Tipps für TINA TI

Tasks

- You can find exercises for this video in the following chapter

Introduction to Online Circuit Simulator - Explanation, Example

In addition to TINA TI, another simulation tool is used in this course: The Online Circuit Simulator.

This tool can help to better understand the currents and voltages in different circuits. The program displays the current flow and the applied voltage in animated form. Under „Circuits“ and „Operational amplifiers (OPVs)“ you will find various circuits that are useful for this course.

There is an English Manual available from the University of Memphis. The Source Code of the simulator can be found on GitHub.

Tasks

Familiarize yourself with the Online Circuit Simulator from Falstad

• first with the embedded example on the right
  • If the circuit is too small, click on Edit » Center Circuit
    If only part of the available space is taken up by the circuit after this, refreshing the browser window (<Ctrl>+R) or editing directly on the Online Circuit Simulator Homepage will help.
  • Most circuits on the wiki are initially stopped. The simulation can be started by pressing RUN/Stop.
  • Check the change in the current flow results when different switches are activated.
  • Change the resistor values by double-clicking on the respective resistor.
• further examples of an equivalent voltage source (Thévenin's theorem) and equivalent current source (Norton's theorem)
  • Search in Circuits » Basics » Thévenin Theorem
  • At the bottom left of the window, you will see two running graphs of the currents and voltages of the two circuits.
    Click with the right mouse button on one of the diagrams and select Combine. The curves should now be directly on top of each other
  • Move the mouse over one of the two voltage sources.
    The respective voltage/current curve is highlighted.
    Are both curves on top of each other?
  • Do the same for the equivalent current source (Norton theorem).
