The supply is 220 V, 50 Hz AC. I need 60 V DC output voltage. For this I need to fire the thyristor at 80⁰. The main problem is to fire the thyristor at 80⁰. Please suggest me the firing circuit for half wave controlled rectifier.
Vdc = Vm(1+cost)/2*pi
where: t = firing angle
Vm = maximum AC voltage
Vdc = output DC voltage
So for Vdc = 60 V, Vm = 1.414*220 = 311
t=?
The required firing angle would be 80⁰. So please help me how I can fire the SCR at an angle 80⁰.
