3 ways of transient processes, in LRC circuits

Click For Summary
SUMMARY

This discussion focuses on understanding transient processes in RLC circuits, specifically the three types: critically damped (ζ = 1), underdamped (ζ < 1), and overdamped (ζ > 1). The user successfully observed these transients using a National Instruments oscilloscope and seeks guidance on parameter values to visualize all three processes within the same circuit. The damping factor plays a crucial role in determining the circuit's step response, influencing the visibility of oscillations at higher frequencies like 50 kHz.

PREREQUISITES
  • Understanding of RLC circuit theory
  • Familiarity with transient analysis in electrical engineering
  • Experience using oscilloscopes, specifically National Instruments models
  • Knowledge of damping factors and their impact on circuit behavior
NEXT STEPS
  • Research how to calculate component values for critical damping in RLC circuits
  • Explore methods to visualize underdamped and overdamped responses using oscilloscopes
  • Learn about the effects of frequency on transient response in RLC circuits
  • Investigate the mathematical models for transient analysis in electrical circuits
USEFUL FOR

Electrical engineering students, hobbyists experimenting with RLC circuits, and professionals analyzing transient responses in circuit design.

Hello!

For those that were with me at signals, I passed the exam, but barley. 10,5 points out 20. Going to cancel that exam and do it again when I have the chance.

But anyway, back to the topic.

I am trying to get the intuition for transient processes in RLC circuits. I was taught that 3 exist, each of them represented by different solutions from differential equation.

When I connected an oscilloscope in National instruments, to a RLC circuit, when I turned on the circuit, I saw the transient process. It was like magic to me.

Can anybody give me good parameters, or a guide so I can see all 3 transient processes in the same circuit but with various values for RLC?

Thanks

The circuit's damping factor

will determine the RLC circuit's step response. I don't know what component values you have lying around, but use what you've got to and solve for the critical damped case (ζ = 1), underdamped case (ζ < 1) and overdamped case (ζ > 1)?

I wanted nice values in relation to frequency, because, oscillations and transients are not very easy to spot at 50kHz.

Guess I will figure them out of that formula, thanks.
