Modify given Problem by using a DIAC with a ± 2-V breakover voltage, in place of the 100-Ω resistor, to trigger a TRIAC. The source is now a bipolar ± 5-V square wave of the same period as Figure.
a. Find the range of R to provide a 5% to 95% on time.

b. Plot the voltages across the capacitor, load, and TRIAC.

c. What is the average power delivered to the load?

Problem
Figure shows an SCR used in a circuit to provide variable electrical power to a resistive load from a high-power square-wave generator. The SCR trigger voltage is 2.5 V.

a. What is the range of R to provide 5% to 95% on time of the SCR?

b. Plot the voltages across the capacitor, load, and SCR for a 50% on time.

c. What is the average power delivery to the load at 50%?
