@ Squidsoft, Thanks for the reply. I understand the cylindrical area part. i did a little research on the topic and found another interesting example for explaining this closed line integral. It has similar views based on Waht's reply.
From my little research on Closed line integral i...
Thank you all for your replies, Now that the concept of line integral is clear,I have another doubt. When we consider a closed line integral, what is the area that we are evaluating?
Is it the area enclosed between the curves, I doubt it.
Thanks in Advance
Hello Everyone
I have a few questions regarding line integrals. First what are they? What is the difference between them and the normal integrals? For eg, The normal integrals can be easily understood by visualizing the area bounded by them, in the same way is there any way as to visualize the...
No am not. My Sine wave is from an IC only. just 2V peak. Which of the method you suggest would be more accurate? The one with capacitors or with the Op-amp because this is one of the crucial steps in my project and i don't want it be less approximate.
Thanks for the replies
@Berekman's Quiz question
Is it like f=(1/2*pi*R*C), where f is the value of the frequency that the circuit has to allow.
In my case source is 0f 50 Hz, so i should substitute 50 in place of f and calculate values for R and C.
now that i have only one equation, i...
Hello
I have a question regarding DC offset addition. I have a sine wave of Peak amplitude 2V. Now i have a DC signal of 0.4v. How do i add this DC signal to my sine wave?
Similarly I'm having another sine wave of 2Vpeak but phase shifted by 180 from the first one. Now again i have 0.4v DC...
Thank u everyone. Now i got a clear idea of the difference between amplification and shifting the waveform. I'll be needing only the amplification part.
Oh!. Now i get it. Thank you Skeptic2.
@John Creighto
The application is i'll be having a DC voltage and 2 sine waves which are 180 degrees out of phase. Now I'm required to add the DC voltage to one of them and subtract it with the other sine wave. Just like an amplifier of gain 1.4 goes...
@Averagesupernova
No I'm not talking about amplifier.
@skeptic2
Yeah you got it right. But just a small variation. I don't want the output to be 7V and -3V, instead it should be 7Vpeak and -7Vpeak. Is that possible? because it is a sinusoidal signal and should be symmetrical.
Hi
I've learned about voltage adder circuits using op-amp that add two or more DC voltages.
But is it possible to add AC voltage with a DC voltage? What i mean is can we add (for eg 2V DC with a AC of 5v peak value,50hz) so that the output is again AC with peak of 7V and frequency is 50hz...
Hi everyone
Before implementing the hardware part of my inverter i simulated my circuit using Simulink(MATLAB). I used a DC input source of value 55v, MOSFETS as my switching devices,PWM method for triggering them and output load of 50ohm. I've attached a screenshot of my output voltage.
Now i...
Thank you all for the help.
Will check out informations about IGBT and others.I still have some doubts, will post it after going through the datasheets.
Thanks again
@ Berekman
PWM is just for switching the MOSFETS. When i compare a sine and a triangle,square pulses are generated. These pulses are used as switching signals and are given to the gates of MOSFETS.I've attached a pdf file giving a overview of how PWM is used in inverters to obtain output...
Thanks for the reply .
@ravioli
I'm really sorry for my grammar and spellings. English is not my mother tongue.
@ Berekman
Yes full bridge inverter is H-bridge inverter. Sinusoidal PWM means I'm comparing a sine wave and a triangular wave for generating PWM pulses.
I have my input voltage...
