Objectives:

• Checking thyristor performance in AC and DC circuits
• Studying the behavior of the UJT transistor
• Using the UJT transistor to start the thyristor employing a pulse transformer in two modes of connecting the load to the power supply and connecting the load to the ground, and using an optocoupler
• Examining the practical circuits of Triac and Diac
• Investigating the performance of SCR and getting to know the effect of the firing angle and investigating the behavior of resistive and capacitive and self-loads in thyristor circuits.
• Investigating the effect of the firing angle on the output power, two-phase full-wave rectifier with resistive, capacitive and inductive loads and investigating the effect of the commutation diode on the two-phase full-wave rectifier
• Familiarity with fully controlled and semi-controlled thyristor bridge circuits with resistive, capacitive and inductive loads and investigating the effect of commutation on inductive load in semi-controlled bridge with commutation diode
