I understand that you're interested in simulating and graphing waveforms for different firing angles using Flux as the software of choice, even though it doesn't have built-in support for circuit simulation. I'd like to suggest an alternate route through simulation applications like LTSpice, Multisim, or MATLAB's Simulink. Here is a rough guide to accomplishing this:
Circuit Definition: First, consider modeling the circuit in the simulation software. The model will include a thyristor (Q1), resistors (R1, R2, R3), a diode (D1), and a transformer (T1). Connect these according to your schematics.
Firing Angles Adjustment: Next, prepare your simulation to utilize three different firing angles, which usually requires configuring a pulse voltage source with a delay equivalent to the desired firing angle. For instance, a 90-degree delay equates to a time delay of 1/4 of the period of your voltage source.
Simulation Execution: Execute three simulations, each one with one of the firing angles that you have outlined.
Waveform Graphing: After the simulations run successfully, you can graph the waveforms of the load and thyristor voltages. Most software applications will let you plot these waveforms over time directly within the system.
It's important to keep in mind that the exact procedure will vary based on the specific simulation software you select. Additionally, understanding the functionality of thyristors and particular details about the circuit will be essential in identifying the correct mechanical switches in the simulation and the required parameters for these simulations.
