Discussion Overview

The discussion revolves around devising a circuit that incorporates a silicon-controlled rectifier (SCR) controlled by Agilent Vee. Participants are exploring the operational characteristics of SCRs, particularly in the context of AC circuits and gate voltage application.

Discussion Character

  • Exploratory, Technical explanation, Homework-related

Main Points Raised

  • One participant expresses uncertainty about the firing mechanism of SCRs, questioning whether it simply means the SCR turns on at a specific voltage and current, and how this affects the AC waveform.
  • The same participant seeks clarification on how increasing the gate voltage alters the positive wave in the circuit, as depicted in an attached image.
  • Another participant suggests a Wikipedia page as a potential resource for understanding SCRs.
  • A follow-up post indicates that the participant has reviewed the suggested resource multiple times but still finds the information unclear regarding the circuit design.
  • A request for further assistance is made, indicating a lack of responses or clarity on the topic.

Areas of Agreement / Disagreement

The discussion appears unresolved, with participants expressing confusion and seeking clarification without reaching a consensus on the operational principles of SCRs or the specific circuit design.

Contextual Notes

Participants have not established clear definitions or assumptions regarding SCR operation, and there may be gaps in understanding the relationship between gate voltage and circuit behavior.

Who May Find This Useful

This discussion may be of interest to individuals working on circuit design involving SCRs, students seeking clarification on SCR functionality, or those using Agilent Vee for electronic control applications.

This really isn't a homework problem, but it is somewhat. Please move it if you see fit.

I need to devise a circuit with an scr in it, to be controlled using Agilent Vee.

Unfortunatley my teacher isn't the best, and I am not completely sure on the properties of SCR's.

I understand that at a particular voltage and current the SCR will "fire". Does this just mean that it turns on when that voltage is applied? Which would make it cut out all of the negative wave lengths on an AC circuit?

In the attached picture it shows the positive wave being altered, does this happen as you increase the voltage applied to the gate?

Ive been scouring the internet and I am still lost!

Ive read that a bunch of times, maybe something just isn't clicking. I still don't understand how to produce what's in the picture.
 
anyone?
