1. For a full wave rectifier, SCR acts like a diode where you cannot stop it as soon as conduction starts. T/F 2. For half wave rectifier, SCR behaves exactly like a diode during conduction mode. T/F 3. SCR stays off until a gate pulse is applied while VAK<0 where A=anode, K=cathode T/F 4. For diode, we control the turn ON point, but only turns OFF when circuit conditions force it to. TIF 5. In a periodic steady state, the average voltage of an inductor is always equal to ZERO. T/F 6. For a phase controlled converter, we cannot regulate the output voltage by varying firing angle a. T/F 7. During commutation period of a single phase full wave rectifier, only ONE PAIR of diode conduct. T/F 8. Diode can sustain a negative current. It will definitely turn ON. TIF 9. Diode cannot sustain a positive voltage. It will definitely turn ON. T / F 10. I like Power Electronics Course. Τ / F
