    help with IR2110 chips

    yes worked it out with google can you help me with the new transformer 40 : 230 and then keep the load which is a motor but if you remember you used an inductor to model the 15watt motor and also work out the max power that this circuit produces please? and the current too?? good to see you...

    help with IR2110 chips

    so I removed a couple of diodes I want to change the transformer to 40v : 230v but have the motor still at 15watt how do you think the circuit is looking!? were do I measure the power out that the coils produce?? I'm looking to get 20watt

    help with IR2110 chips

    so I've found if I set the logic supply equal to the signal voltage, the logic supply = 5v, and signal voltage = 5v or logic supply 3.3v and signal = 3.3v then it runs! but not if the logic supply is 5v and the signal voltages are 3.3v !

    help with IR2110 chips

    bearings turn up Monday will have pictures soon also read this "A real chip should not be operated without logic supply! But the supply voltage must be correct, e.g. 5V for a 5V input signal." I'm a bit confused!

    any ideas guys? so I found on edaboard that you can connect vdd to vss via 100nf cap and it works fine!!!

    help with IR2110 chips

    I found something!! the circuit seems to only work when the 5v supply to the VDD on the IR2110 chips, has no ground, and effectively not wired in, can anyone explain why?? thanks I think it works perfectly when the 5v supply is not wired in and so am thinking of just not putting it in! still not...

    help with IR2110 chips

    after 200ms the spikes even out to just over 20watts when measuring power over the 1ohm r9 resistor before going into the main circuit so have I achieved the 20 watts desired

    help with IR2110 chips

    sooo... is that recommended? also should the current be constant or is this properly how it should be?

    help with IR2110 chips

    waiting for bearings for the trolley wheels, will have pics soon! I should be able to achieve at least 15 volts on each coil with minor modification, and I happen to have a 15v : 230v transformer; and so I'm considering just keeping the volts low and have max current, is this recommended? - I...

    I had a go but think that its wrong

    help with IR2110 chips

    hmm going to get more voltage out of it making modifications can you set it up how it will look in spice with the 2 sets of 4 coils (connected in parallel) and then those connected in series
