TINA/Spice: Steady-state output.

Hi Gannamraju,

The  voltage and  currents on some modes is shooting up to giga volts and terra amps which is causing the convergence issues. You might want to check what is happening at that point. Also is T3 connected as expected?

Kaushal,

There is some improvement but your symptoms are still the same. The voltages are still going up very high. To see the voltages, when you get the convergence error, click on "Ignore" and "preview" your results. Unless you fix this root cause, the issue may not go away. Changing the timing on the pulse will only change the time at which the convergence occurs.

For PID, you can do a google search. Following is one example: www.ecircuitcenter.com/.../pid1.htm. All these blocks can be found under the sources tab. Using the Controlled Source Wizard is especially powerful. I would recommend going through the training below if you are new to TINA-TI.
For Summer, your question is already answered here: e2e.ti.com/.../622347

If you are using the in built voltage generator, you can simply use the phase field to shift the signals.

If you are generating the PWM signal yourself, you will need to have a known reference signal at the frequency (like a sawtooth) with a known amplitude. Then use the voltage on the sawtooth to trigger the phase shifted voltage.

For example, if you want 2 PWM signals - phase shifted by 120 degrees, create a sawtooth with 3V amplitude. The 1st PWM signal should be generated when sawtooth is at 0V, the second one should be generated when sawtooth is at 1V to give 1V/3V * 360 degrees = 120 degrees of Phase shift. The mechanism to generate the PWM will remain identical for both signals.
