Question

Fill in the blanks A) The three terminals of the SCR are the For the SCR to begin to conduct, it must have a and current applied while it has a positive anode-to-cathode voltage. B) After conduction is established, the gate signal is no longer required to maintain anode current. Answer: True or false C) Design a Controlled Half-Wave Rectifier circuit to produce an average voltage of 45 V across a 100 Ohms load resistor from a 120-V rms 60-Hz ac source. Determine the power absorbed by the resistance and the power factor. Draw the circuit

Explanation / Answer

A) the three terminals of SCR are cathode anode and gate. In order to be in conduction mode gate current called triggering current with positive anode to cathode voltage.

B) after conduction is established the SCR remains ON even if we remove the gate current. Therefore it is true
