    help with IR2110 chips

    how do I work out the dead time from this?

    Okay I think Ihave the gate capacitance Ciss is 1850pf yeah I really need an extra nudge, cheers

    help with IR2110 chips

    Okay so that means abolutely nothing to me but thanks for the answer also do you recon the transformer I have (300watt 230v transformer) will be in micro or milli henrys and I see something about dead time. what does .tran 100m mean. I aso am still trying to determine if, is gate capacitance the...

    help with IR2110 chips

    thank you I've figured it, now I need to know is gate capacitance the same as input capacitance, output capacitance or feedback capacitance and also I need to know how to setup an anti-phase signal

    cool as a cucumber, cheers im going to try now Okay I have the turn ratio as 4.2 so the inductance ratio is 17.64 (where do I enter this value) also primary resistance is 0.25ohm and the secondary is 4.85ohm. I'm on the datasheet, am I looking at the input capacitance, output capacitance or...

    Okay so today I will be builing the circuit in ltspice to get the simulation working, then worry about actual values later (because I will be builing at some point) thank you for your help. I still want to design the transfomer, any ideas on that, for the sim sake? ok I have made the circuit in...

    help with IR2110 chips

    To be honest I'm winging it so I'm not too confident at deviating from the given values in the picture thank you for your help! for example do the resistors have to be quarter or half watt. I wanted to use for the electrolytic capacitors 22uf 100v, will that suffice aswell, I'm not sure how to...

    the turn winding ratio is 1:4.2 therefore 55:230 the transformer is made by vigortronix 146-300-255 k = coupling factor parameters of the inductors L - inductance of the primary in henrys (open - nothing connected to the secondary) Resistance of the primary winding L - inductance of the...

    help with IR2110 chips

    no im correvt. if you have 55v through the first wire 55-0 and then it comes out the centre tap you connect the second 0-55if you parrallel so the turns ratio stays the same but there's less resistance, connecting the centre tap on the 115-0-115 makes the trqnsformer 1:4.2 I'm using as step up...

    this is post 41 and I don't see it ok yes sorry I got confused I see now, thanks again yes sorry about that I have a 146-300-255 toroidal transformer as a step up transformer and I want to model it in spice, the primary side is 55-0-55 and will be in parallel, the secondary is 115-0-115 and...

    help with IR2110 chips

    sorry about that i will go back and look, one thing is that I'm looking at the circuit and there are 4 more caps c3 and c4 and c6 and c7 in the picture

    cool, nice weather? whats the time there? do you think that you can re-label the blury picture if you want to, if you don't mind?

    help with IR2110 chips

    thats where I got the original image, I cant zoom because it blurs, and can't click through the image because of the internet connection I have sees the website as a threat, I need to know the values of the parts where are you from just out of interest?

    help with IR2110 chips

    can you make out the values for the 8 resistors 6 diodes 8 capacitors in the picture I can make out the pins for the IR2110 and I have chosen the MOSFETS as IRF640 N-channel perhaps (if you can make it out) you can modify the blurry parts out in paint and write over them with with a text box...

    help with IR2110 chips

    thanks but no, it's still blurry when zooming in can you get me a clearer image please? also could I have the image early in the day because I want to get on with building the circuit in the design simulator? thanks, awaiting your responce.
