Hey all, I have a question regarding simulation of a precision full-wave rectifier circuit ( using op-amps ).
I have done a lot of research and still cannot get the issue resolved. I am using multisim 11 if that helps.
My professor ( he never taught a thing about it by the way ) asked me to create a precision full-wave rectifier with an input 110(√ 2) sin(2∏60t). In other words he wants about 155 volts if I am correct at 60 Hz, to give a full wave output using op amps. In my attempts, I have simulated a precision full-wave rectifier that works perfectly, but only when I use 1 volt input, anything above 5 and the output is ridiculous. I have attached my simulations thus far. The first image the output isn't working as it should, while the second one, I am getting a half-wave, I have even reversed a diode to opposite polarity and it does not help.
I am not asking for anyone to do my project or anything, but would like to be pointed in the right direction, as this professor just came out of a coma, and for whatever reason they allowed him to "teach" electronics 2.
Thanks in advance!
