    Problem with simulation

    i mean to change the 360 ohm resistot to 1K and i kept the 470 ohm resistor in her place .yes the neutral connection of the motor is arriving from the sector

    Problem with simulation

    the input of opto is ok , i have 1.2V which it has the marge 1.15V and 1.5V but the output of opto is 18V and the output of triac is 18V

    Problem with simulation

    i used this BTA06 https://www.farnell.com/datasheets/1723943.pdf?_ga=1.102352577.1165230256.1456677198 i simulate the program with proteus isis and it is working correctly

    Problem with simulation

    Hello, i'm doing a project to control a motor with a circuit witch i send it in a PDF: a part of alimentation 5V a part of order is the pic16f1508 a part of interface with the network RS485 a part of isolation with the MOC3023(OK3/OK4) a part of power with the BTA6 (T1/T3) but when i...

    detect zero current of motor ac in order to switch the output of microcotroller pic16

    I am doing a project controlling an asynchronous motor 230V / 6Amax with triac which is controlled by a microtrolleur, now I want to add to the circuit a part to detect the zero-current in motor side caused by the presence of Limit switch and inject the result to the microcontroller, can I use...

    regulator LDO /1A problem

    hi, I used power switching to generate the 5v output to feed a microcontroller the regulation is made by a diode because I have a voltage about 5.34V, so I don't find the right regulator the most of them is working from 6V is it efficient or I have to change the regulation it by a...
