(Half Wave Thyristor Controlled Rectifier)
1.Input any value of Theta ie firing Angle.
for example(taking th =30 degree)
Python Code:-
import numpy as np
import scipy as sp
import math
import matplotlib.pyplot as plot

pi= math.pi
Vm = 220
th = int(input("Input the value of Theta(th) ; "))
print(th)
x = np.arange(0,4*np.pi,0.1)
T_R = np.sin(x - th)
print(T_R)
T_Y = np.sin((x -(th + 120)))
print(T_Y)
T_B = np.sin((x -(th + 240)))
print(T_B)
plot.plot(x,T_R,x,T_Y,x,T_B)
plot.xlabel('x value from 0 to 4pi')
plot.ylabel('Three phase supply')
plot.legend(['sin(0)','sin(120)','sin(240)'])
