I have an Ultimaker and a 3D engraver. It’s a steady looking 3. You only need the anti-parallel diodes if you are driving inductive loads or very long wires. To obtain a low onstate voltage, a sufficiently high gate voltage must be applied. It is an automotive type, plain and simple.

It will give you a good basis for problems in these circuits. Fill in your details below or click an icon to log in: It’s also worth considering that the audience of the question is those who know something about IGBTs and ignition circuits arduino igbt that probably makes it off topic arduino igbt.

Email required Address never made public. Anytime there is current applied to arduino igbt circuit it passes arduino igbt through the igbt, and therefore makes the dyno run at full load. For instance a coil that generates 30kV with a 1: This question does not ardkino to be about Arduino, within the scope defined in the help center. You are commenting arduino igbt your WordPress. That circuit was a VFD which looks like:.

If this question can be reworded to fit arduino igbt rules in the help centerplease edit the question. Without the capacitor there is indeed arduino igbt fat spark across the contact but when it’s included in an inductive circuit it also serves as an essential component of an oscillator. To obtain a low onstate voltage, a sufficiently high gate voltage must be applied. If arduino igbt are unfamiliar with basic electronics you shouldn’t get involved with circuits directly powered from mains.

Gate drive requirements of IGBTs

Vishal No problem at all and of course feel free. R is arduino igbt the total resistive loss in arduino igbt gate circuit of course, but if you add a gate arduio it is usually dominant. Since you want a 20Hz trigger I suggest you measure the inductance of the primary and calculate an initial value of C. The reflected voltage doubles the peak and maybe overloaded it.

arduino – Why this pair of IGBT’s died silently? – Electrical Engineering Stack Exchange

Menu Skip to content. Test equipment, replica and original sci fi props and costume pieces, and whatever else I atduino like at the time. From that you can determine what kind of drive capacity you must supply.

I want to control arduino igbt high load with fast switching times motorbike ignition coil using an arduino. The pair of IGBTs that died: It sounds like you don’t really understand HV electronics, and I arduino igbt you stop before you get injured or worse.

In arduino igbt old style points-based ignition the capacitor was to limit the risetime of the primary voltage to allow the spark to quench on the contact points overwise it would both arduino igbt the contacts and remove all power from the spark plugs. Thanks for the info.

For a n00b like arduino igbt this is weird but for you this might be something obvious. But – you don’t need diodes to drive IGBTs. Any loading on the secondary side will affect the resonant frequency of the circuit so the value of Arduino igbt may need modifying to suit.

MarkT Brattain Member Posts: Why this pair of IGBT’s died silently? Questions Tags Users Badges Unanswered. The secondary of arduino igbt ignition coil remember its a transformer or autotransformer will arc before the primary exceeds a particular voltage.

The IGBT failed when it was ugbt in use, that’s what making me think it’s lightning. See if you can measure the peak voltage draw.

TomCarpenter I arduino igbt feel shame on myself. You arduino igbt nothing to limit inrush current when plugged in to the mains — likely will blow the bridge rectifier also.

Both of your comments on this page ask for repeats of things which have already been clearly stated.
