The point is that the project is doing this with 3 phases, 3 sync voltages and 3 tca785. But using an optocoubler i wouldn't have the same control voltage not? i would turn on the transistor but i wouldn't replicate the v voltage in the another grounded circuit, or
Hi EDA,
I'm doing a 3 wave fully controlled rectifier with 3 tca785's, the issue comes becouse of the control voltage, it should be connected to the pin 11 of the 3 tca785's but, every tca785 has its own ground point for his supply voltage and the control voltage has his own ground point too...
Hi Edaboard,
I have to make a model of this DC motor. There is a datasheet in the main web (https://www.tem-electric-motors.com/download/pdf/r3.pdf "The rightest R3L column"). i can't found the some data values like the viscous friction coefficient "B" or the field winding values...
Hi FvM,
First of all, thanks for your attention. Okey so here it is the schematic of the corrected circuit. I have the same ground reference for the 3 tca785 and the 3 phase referende to the same ground too. If I made different power rails for the sync circuits and for the 3 phase voltage it...
Some ideas?
I fixed the matrix error setting 10Ohm resistors in the transformators output but I can't get the correct rectified signal... I'm getting crazy I don't know what to do... I've tryed everything, putting the 13 input of the tca785 to ground but nothing changed, I've tryed a lot of...
I'm gonna reply to myself...
I have a problem now simulating the rectifier. I've donde all the circuit but i don't know how to solve this problem with ISIS... Any idea?
Here it is the circuit
And here it is the proble :bang:
Hi edaboard,
I'm trying to simulate a three phase full wave controlled rectifier with three TCA785. I have some issues with the design. I saw some rectifiers with tca785 and they use three tca785 one for each phase, but they use the voltage phase-neutral, i'm trying to do this using the voltage...
