Given Information:
Vdc = VF-L = 2.18x10⁶ V = 2,180,000 V
VF-L = voltage at full load
Ripple factor = r = 0.1 %
Voltage Regulation = VR = 0.05 %
Required Information:
Ripple voltage = Vr = ?
No-Load Voltage = VN-L = ?
Answer:
a. Ripple voltage = Vr = 2,180 V
b. No-Load Voltage = VN-L = 2,181,090 V
Solution:
a. Ripple Voltage Vr
The ripple factor is a measure of effectiveness of the rectification (the conversion of AC to DC) and it should be as low as possible.
The ripple factor is given by
r = Vr/Vdc
Re-arranging the formula to find ripple voltage Vr
Vr = Vdc*r
Vr = (2.18x10⁶)*0.001
Vr = 2,180 V
b. No-Load Voltage VN-L
Voltage regulation is given by
VR = (VN-L - VF-L)/VF-L
Re-arranging the formula to find the no-load voltage VN-L
VN-L = VR*VF-L + VF-L
VN-L = 0.0005*2.18x10⁶ + 2.18x10⁶
VN-L = 1090 + 2.18x10⁶
VN-L = 2,181,090 V
VN-L = 2.181x10⁶ V
