How It Is Used
With a small gate current set, the anode voltage is raised until the SCR suddenly conducts; repeating this at other gate currents shows how the gate controls the turn-on point. The anode current is then reduced until conduction stops, and from these readings the latching and holding currents that matter in AC power control are found.
Frequently Asked Questions
What supplies does the SCR Characteristics Apparatus provide?
Two regulated DC sources: 0–30 V for the anode and 0–5 V for the gate, each adjusted with a potentiometer.
Which readings can be taken on the SCR Characteristics Apparatus?
Anode voltage, anode current in mA, gate voltage and gate current in µA, each on its own meter.
