An aircraft electrical system operates at 115 volts at 400 hertz. It is to supply an average d.c. voltage of 28 volts and an average current of 20 A at a ripple factor of 0.005.
Determine: The r.m.s. ripple voltage
Here is my attempt.
Vc= Vs-2Vd
=28-2(0.7)
= 26.6 Volts
Vr= (1/2 x fs x C x Rl )(Vc)
R=V/I 28/20= 1.4
(1/2x400x1.4)(26.6)
= 0.023
Vrms= Vr/2sqrt3 Vrms = 0.0063
Now there's a good chance I'm way of here...Thanks for any help!
