Task 2: Single-phase half-wave phase-controlled rectifier with RL load

Recall Chapter 2,

Make a new project. Build a single-phase half-wave phase-controlled rectifier with

RL load

Use the sinusoidal source in the SOURCE lib set amplitude 450V and frequency

20Hz

Use the pulse voltage source in the PSpice Component and set the rising time lus,

falling time /us, pulse width 100μs, low-side output voltage OV, and high-side

output voltage 201

Use the load parts in the PSpice Component set resistor 50, and inductor 20mH in

series.

Use the thyristor in the ELEC4174_Fall_2023 library.

Use the time domain simulation set up, set run to time as 50ms and maximum step

size as le

a. Show your schematic.

b. If we have voltage pulse (gate signal) appears at 15ms,

1) Plot the voltage across the resistor and voltage across the inductor.

2) Find the conduction angle (approximately) using results in part b.1).

3) Evaluate your plots in part b.1) for maximum value for VR and the point when

V₁ across 0, briefly explain with words or equations what happened there.
