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

[@drnsksai]

Excellent

[@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

[@cyrusmehdipour1018]

Thank you

[@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

[@severussnape5330]

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

[@ravitejayadam2421]

very helpful

[@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?

[@bekirbasarslan7792]

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.
