Each of the following components belongs to one of the two groups controlled conducting component and switching component A controlled conducting component is used for delivering power when it is turned on A switching component is used at the place where the conducting is only momentary for trigging another component Identify the components by label each of them with a \"C\" for a controlled conducting component or a \"S\" for a switching component The given waveform is a current flowing through a component This component must be a Zener diode SUS SCR triac List four types of triac\'s firing mode. What is the difference between breakdown and breakover for an SUS?

Solution

1.)SCR is a \"S\" device that is SCR is a switching component.

UJT is  a \"C\" device that is UJT is a controlled conducting component.

TRIAC is  a \"C\" device that is UJT is a controlled conducting component.

TRANSISTOR is a \"S\" device that is TRANSISTOR is a switching component.

A FOUR LAYER DIODE IS A nothing but a Shockley diode it is well known for its high switching speed.

2.) The current waveform which is shown belongs to triac. That is it is a TRIAC current waveform

3.) The TRIAC operates in four modes by taking With M1 as reference,
1. M2 positive, gate positive, quadrant 1
2. M2 positive, gate negative, quadrant 2
3. M2 negative, gate negative, quadrant 3
4. M2 negative, gate positive, quadrant 4,
A TRIAC can be triggered in both phases of an AC signal so it has this advantage over a SCR.
