Full Wave Rectifier (DC Load Current & DC Load Voltage)

[@DavidSunday-j9b]

A single-phase single-diode (half-wave rectifier is connected to a 240 V, 50 Hz AC supply. Neglecting the diode voltage drop,determine the current waveform, mean load voltage, and the mean load current for a load of a. Pure resistor of 10 Ohm b. An inductance of 0.1 H in series with a 10 Ohm resistor

[@sandyarubiya9214]

Thanks for coming back sir

[@deepchetry2]

Really your classes are so super sir ....

[@pandu7820]

A diode whose internal resistance is 20Ω is to supply power to a 100Ω load from 110V(rms) source pf supply. Calculate (a) peak load current (b) the dc load current (c) the ac load current (d) the percentage regulation from no load to full load. Please answer to this question

[@srikanthreddy549]

In calculating Vdc or Idc , why we're taking time period from 0-π instead of taking 0-2π as we do it in half wave rectifier? Your videos are nice and easy.

[@davidgriffin79]

It's the area under the curve for a half-wave rectifier one half cycle is removed so pi to 2pi is just a gap. However the average voltage will include that gap.

[@Channel_Math_and_Physics]

He forgot to mention one part and that is it's per cycle we calculate

[@pogu9835]

You are a life saver sir

[@anumkhan4071]

in previous lecture you have explained significance of rms value i.e. it is equivalent to dc value. but here you have told that average value is dc value. kindly explain this.

[@Tarun_Kotagiri]

Yeah..I was wondering the same thing

[@Justchilllllla]

@@Tarun_Kotagiri Brthr,You are confusing with the DC current and The "DC component" in total output current. In the rectified total output current,there are two components AC as well as DC like this I= I(AC) + I(DC). Now I(AC) does not contribute in average value because Average value of AC current over whole time period is zero,Hence it's the DC component only which contributes in the average value of rectified current... So in case if rectifier we can write I(AVG) = I(DC). Also I'm still learning,so the above explanation might be wrong please please correct me if you have better explanation,I'll be thankful to you...

Thanks a lot sir!!!

[@hm2715]

Still very confused about DC voltage and current.. Sometime you mentioned RMS is equivalent to DC, sometimes Avg to DC.... Can someone genuinly help...

Integrate must be 0 to pi and - pi to 2pi

[@muhammadhassaansiddiqui4239]

thank you yar

[@sonusambharwal8828]

Super sir....

[@AnanyamsPatel]

Hello Sir, If there is a capacitor in parellel with load resistor, should I calculate impedence in order to find out DC load currect? Thank you,

[@vedurubhavanireddy9221]

Why you are dividing with 2π in half wave rectifier and why you are dividing π in full wave rectifier

[@lolasolomon1054]

If i’m watching these videos and not solving problems in any book .. is that ok? Or can u recommend me a book that i can find good problems in it?

[@TusharMazumdar]

you integerated from 0 to 2.pi in case of half wave rectifier but 0 to pi in full wave... why so..?

[@hichembenamara4710]

i think because the periode here is pi while in half wave rectifier we had a periode of 2pi

[@Amrhossam96]

let me explain the Average is Vavg=1/2Pi Integration from 0 to 2Pi Vm Sin Omega T but as you see in this case the function is even harmonic which repeats it self 2 times in the period so you can integrate half the period which is 0 to PI and multiply that by 2 this 2 will cancel out with the 2 in the denominator and it'll become as it's written message me if you still don't understand

[@dazzling_kd]

Amr Hossam but the limit changes π to 2π . then how it gets cancelled

[@bhanuchandu9820]

Amr Hossam bro didn't understood what you have said

[@aram8832]

it can be integrated to 0 to 2pi but we have to divide by 2pi instead of pi. Btw gives same answer

[@saikeerthana4809]

Why we have taken 1/π Why we have not taken 1/2π as we taken in halfwave rectifiers..!?

[@pranaysagar5349]

Sir is what about filters ..

[@kaushikbudi6958]

sir in halfwave retifier you took x-axis as t but here it is wt why

The average voltage is the area under the curve.

[@rickperez8975]

Why do we ignore w in the sin(wt) when taking the integral?

[@balaji2.095]

We are not ignoring Since we are integrating the equation with wt So we substitute π and 0 in the place of wt

[@makshithsaai2821]

sir why average voltage and dc voltage are same

[@blzKrg]

Because a dc voltmeter shows you the average voltage of the time varying voltage signal. That is why average voltage is called dc voltage.
