    help with IR2110 chips

    so I've double checked the connections, it appears to me to be perfect to me, I would have made it more symetrical but couldn't flip the IR2110's or mosfets IRF640 I dont mind building it again its good practice but I would like the IR2110 lib file if you can great what are sub and asy not...

    its difficult to check the circuit so i'm going to try it again, can you supply your .lib file for thr ir2110 please? then we can be on the same page also is the .lib file for the IRF640 good?

    running one more time to check that I told you right, can I have the model you use please may remake again also the ringing is on both not just blue its directly underneath the blue

    so it appears as whats know as noise is happening any idea how to reduce it

    I think the whole circuit is crap there's no fluctuatio on the signal lines and I don't know why there isn't any fluctuation on the input to the primary of the transformer start from scratch? as far as I can tell it should be correct to be fair I don't know why it doesn't work, could it be...

    is this correct??

    help with IR2110 chips

    I think I have dont the pulses wrong because when I click to measure the pulses strait from the pulse sources it's flat-lining any suggestions?? the outputs are at 9uV the, both of them and they're not fluctuating as desired and the wire connected to the inductor looks like this

    so i tested it, on first attempt I dont think it worked lol at least its doing something though that is good I suppose

    I have learned about how you reached 15watts from 230v 10ohm internal resistance and frequency of 50hz and 0.6 henry's for the motor. And I am impressed with the working and so I would like to thank you again because you havn't got to help me, but still are, I appreciate your help. Is this...

    brilliant thanks just one last thing to get, what is the dt bit about how did you get it to say that away from the pulse sources up to the left on your picture you sent me, about the part in the curly brackets - something to do with that So, for yourself, can you download the .asc file and try...

    I dont know how to set up the dt bit but I have done as you suggested and put a 0.6h inductor with 10R

    help with IR2110 chips

    Okay you gave some numbers for pulses a while back should I just use those, I dont know how to set up the dt bit. In the picture is 0Vinitial 10 Von ?

    I know you given me this link https://electronics.stackexchange.com/questions/234290/using-a-single-phase-induction-motor-equivalent-circuit-in-ltspice butI don't really understand it. It's the final part of my circuit and I need to grasp it I think the information I need is in this link but...

    help with IR2110 chips

    Okay thanks I appreciate what your saying but still dont understand doesn't the voltage switch between (V initial+55) and (Von+55v) or is it (V initial 0) and (Von 55v) nevermind I get what your saying inital is 0v and on is 3.3v so how do I set the other parameters T delay T rise T fall T on...

    1850pf yes you are correct 1.85nf. I couldn't work out how to set up the voltage sources to give square waves and apply the anti phase and dead time. I'm not certain how. also i think that because its a sqare wave the rms equals peak voltage?

    help with IR2110 chips

    now I'm confused if the high voltage side ie 230v side is equal to 1henry then the primary side would be sqrt of 1 which is one. this probably sounds super stupid might it be roughly 31mH? Okay lets do the signaling part first I'll tackle the motor after. the gate capacitance is 0.1850nf how...

    also at the other side of the transformer (output) there is going to be a 230v 15w ac motor single phase, how do you simulate that?
