    help with IR2110 chips

    I dont get it if I'm using 55vdc and inverting it then the out put should be 55vac multiplying by the transformer ratio 1:4.2 gives 230vac

    even though the input voltage to the inverter is 55vdc?

    help with IR2110 chips

    I am not talking about stepping down mains to then rectify with filter caps but thank you for trying I'm talking about rectifying the AC voltages from the coils on my machine putting a smoothing cap, inverting that DC voltage (which is 55VDC) to 55VAC and using a transformer to step up the...

    funny you should say that I've just been trying to mess about with spice, I don't know how to model my machine, so first step, going to take measurments of the coils raw ac put them through the rectifier (in spice) and set the frequency and put in the capacitor bank, so that's the plan for the...

    cool did you get what I meant when I said that the that the potential in the capacitors would collapse a moment after attaching the transformer to the circuit? because apart from the primary coil's resistance it's basically a short! what are your thoughts on this please?

    help with IR2110 chips

    I have a feeling that when I connect the transformer the potential difference that build up in the caps will collapse and come to a resting voltage but I have a plan measure the output of the transformer divide it by the transformer ratio get that digit and divide 240 by that number that will...

    I will still test both the square wave and the sinosoidal!

    Hello, Counting the delays in the seqence, i woud say it is for 50 hz Bertus and you say it has built in dead time because I really don't want to be builing the circuit again! :)

    so another question is this 50 or 60Hz /* This code was based on Swagatam SPWM code with changes made to remove errors. Use this code as you would use any other Swagatam’s works. Atton Risk 2017 */ const int sPWMArray[] = {500,500,750,500,1250,500,2000,500,1250,500,750,500,500}; // This is the...

    I'll try both the square wave and the sinosoidal wave see which is better its just a matter of reuploading code but I do want at least 2 micro-seconds dead time though, I was under the impression that square wave would be more efficient becuase the practically keeping it's "on" for a longer...
