## Creating and simulating an RLC circuit on the Raspberry Pi 5 single board computer using TINA

In this video  we will create and analyze an RLC circuit on the Raspberry Pi 5 single board computer with TINA.

First you have to install the Wine Windows emulator available from the PI-Apps application.

If Wine setup is complete you will see it in the Raspberry OS main menu, so for example you can launch the program WineCfg to configure the optimal text size of the emulated Windows applications.

Assuming you have Wine working in 64-bit mode, you can start the installation of TINA. After completion of the TINA installer, you’ll find TINA in the Raspberry OS main menu (if not in the first level menu, look for it in Wine applications) so you can start it from there.

##### Creating the RLC circuit

An RLC circuit is an electrical circuit consisting of a Resistor (R), an Inductor (L) and a Capacitor (C). After creating the circuit, we change the default values of some of the components.

##### Transient Analysis

We Set End display time to 50 microseconds, then select the “Zero initial values”option. Next, we add the diagram to the Schematic Editor window to store it together with the circuit schematic.

###### Symbolic Analysis

After that, we generate the accurate closed formula describing the transient response using the Symbolic Analysis capability of TINA. Note that the closed formula exists in linear circuits only. The symbolic result describes the transient response of the circuit with an accurate analytic closed formula.

In the following, we will show, how to Draw a diagram using the formula and compare it with the numerical result.

##### AC Analysis

In the AC Transfer Analysis dialog, set the number of points to 500 to have a finer diagram. Using the checkboxes in the diagram group, you can determine which diagrams will be displayed. Check them all.

The AC Amplitude Characteristic appears, but at the same time the program has calculated the Phase, Nyquist, Group Delay and the AC Bode diagrams.

###### Symbolic Analysis

Finally, we generate the closed formula of the AC Transfer Function using Symbolic Analysis.

## Online Design and Simulation of the Semtech TS30012 DC/DC Switching Regulator Circuit

In this video we demonstrate the online design and simulation of the Semtech TS30012 DC/DC synchronous switching regulator evaluation circuit using TINACloud.

##### Startup Transient Simulation

The startup transient of a DC-DC converter is the period of time during which the converter is transitioning from its off state to its steady-state operating condition.

##### Redesigning the circuit

Let’s redesign the circuit to generate a 3.3 V output voltage.
The Design Tool changed the RTOP resistance to 26.7k and displayed a quick diagram of all the relevant analysis results, based on analytic calculations.

Steady state analysis of a DC-DC power supply is the analysis of the circuit’s behavior when it has reached a steady state. This means that the output voltage is constant, except for the ripple voltage, and all the components in the circuit are operating in their steady state conditions.

##### Line Step Analysis

Line stepping analysis of DC-DC converters is used to determine how a DC-DC converter responds to changes in the input voltage.

Load step analysis of DC-DC converters is a type of circuit simulation that is used to determine how a DC-DC converter responds to changes in the load current.

##### Comparison of simulation and measurement results

The simulation results show good agreement with the voltage measurements in the TS300012 datasheet.

##### AC Analysis

AC analysis is a powerful tool for designing and optimizing DC-DC converters. It provides the frequency response of the converter, which can be used to analyze its stability and performance under different conditions.

##### Efficiency Analysis

TINA and TINACloud also allow fast and accurate calculation of efficiency as a function of load current.

## Online Design and Simulation of a Würth MagIC DC/DC Switching Regulator Circuit (171033801)

In this new video we demonstrate the online design and simulation of the Würth MagIC (171033801) DC/DC synchronous switching regulator evaluation circuit using TINACloud.

### Startup Transient Simulation

The startup transient of a DC-DC converter is the period of time during which the converter is transitioning from its off state to its steady-state operating condition.

In most simulators the Startup Transient simulation takes a long time since the whole process from the initial state to steady state is simulated.

However due to the built in average model in TINA and TINACloud the simulation takes only seconds both online and offline.

TINA and TINACloud can also be used to perform switching mode transient analysis. Due to the advanced multicore solvers in both software, switching mode transient analysis is still quite fast and results in more detailed waveforms.

In addition, TINA and TINACloud include a very fast calculation of the ripple voltages using the combination of the average and switching models.

The simulation results show good agreement with the voltage measurements on the datasheet:

Steady state analysis of a DC-DC power supply is the analysis of the circuit’s behavior when it has reached a steady state. This means that the output voltage is constant, except for the ripple voltage, and all the components in the circuit are operating in their steady state conditions.

TINA and TINACloud provide a very fast and accurate method for determining the ripple voltages in any circuit. They use built-in average models to quickly reach the steady state and then switching models to determine the ripple voltage.

This method allows a very fast determination of ripple voltages for any circuit settings without the need of storing initial values of inductors and capacitors in the circuits.

### Line Step Analysis

Line stepping analysis of DC-DC converters is used to determine how a DC-DC converter responds to changes in the input voltage.

TINA and TINACloud can simulate the circuit response extremely fast due to their built-in average models.

Load step analysis of DC-DC converters is a type of circuit simulation that is used to determine how a DC-DC converter responds to changes in the load current.

In TINA and TINACloud you can also quickly simulate the circuit response to a load step.

### AC Analysis

The built-in average models of DC-DC converters in TINA and TINACloud allow fast and accurate AC analysis.

AC analysis is a powerful tool for designing and optimizing DC-DC converters. It provides the frequency response of the converter, which can be used to analyze its stability and performance under different conditions.

### Efficiency Analysis

TINA and TINACloud also allow fast and accurate calculation of efficiency as a function of load current.
