Umanand sir is an absolute legend.

[@deepakbhangadia8693]

Very good explanation. would request to kindly make a video on LC filter after bridge rectifier.

[@rohanthole8245]

capacitor equation be useful for 3 phase uncontrolled rectifier filter design

[@debojitacharjee]

For rectifier circuit the filter capacitor formula is C=I/(2*f*Vpp) I is current, f is AC frequency and Vpp is ripple voltage. I want to know whether we can take the value of "I" as per the load requirement or it will be the transformer supply current???.

[@sayansarkar1196]

how Vm2 = Vm1* cos(alplha)?
please explain

[@drnsksai]

Excellent

[@aboabdellah9639]

Excellent pedagogy, very useful informations. I have a question about Im (the maximum current in the capacitor, in the m file it is (Im=Io_max*pi/a_min)!?
Thanks

Great video but I did not get how did he obtain T/2 term at 13:50 ?Please answer.

[@mihrdave37]

Can i use this calculation for designing input capacitor for pv system.
IN which input capacitor is connected between pv panel and dc dc converter?

Thank you

very helpful

Hello, can you share c code? Good luck!

[@nadiabeno467]

tell me how to find alphaa ??

[@aboabdellah9639]

Hello, the angle Alpha is simply depends on the voltage ripple (Vr):
from the figure: sqrt(2)*Vi_rms*cos(Alpha)=(sqrt(2)*Vi_rms-Vr), this implies that: Alpha=acos[(sqrt(2)*Vi_rms-Vr)/(sqrt(2)*Vi_rms)].

[@catalin3407]

Let us place the origin at the top of the wave. We then have a rectified cosine wave of equation |Vm1*cos(w*t)|.
ripple=Vm1-|Vm1*cos(PI/2+PI/2-alpha)| where |something| denotes the absolute value of that "something" because the cosine wave goes rectified.
