You want a defined startup state. Could it be an issue that the negative current is specified at mA and the gate discharge current happens to be higher than that and goes directly through the driver burning it? Typically driver in one of the phases fails. Bogumil I’ve never seen such configuration.

In order to optimize your browsing experience Infineon uses cookies. However after reading ir211 application notes I will try to find exact ones it seems having these resistors is a good idea as means of protecting the driver ir2110 higher R means ur2101 maximum current. The extra diodes across the gate resistors is only adding to the capacitance problem as well as adding a switching delay and a path from the switching transient voltages to get back to the if2101.

Find an answer to your question Unfortunately, your browser does not support embedded frames iframes: I have a few theories about what may be the problem but I have not been able to pinpint exactly what it is because I think it has something to do with a transient condition that happens very quickly not giving me enough time to see it on the scope.

The gate resistance ir2110 way to high ohms, the parallel resistors R17 and R18 are not supposed to be there, as they just spoil the or2101 of the bridge. I was able to spin up the motor to speeds at which it draws 5A and do instant spinups from zero to full throttle as well as instant stops without burning anything so far. I have also been using 0.

How would you handle it externally for a 3 phase motor 3 wires, star configuration?

The middle ir21101 continued to switch as normal – the broken ones went into locked state with both mosfets switched on causing a short on the power rail. The motor spins up to a certain point, then as I increase the motor speed current increases as well one or more of the drivers fail. Should I maybe use a larger resistor in series with the gate to protect the driver against possible reverse currents?

Irr2101 think it is early to say whether this really did make the issue go away completely but after more tests today no driver chips were burned.

Where have you seen resistors ofit could be that they were 3. I have seen schematics using resistors. Post as a guest Name. This site uses Akismet to reduce spam. Thanks for your feedback. None of the mosfets have failed so far though. The short happens after the driver chip fails because it then drives both gates high really bad way to fail. I suspect an inductive spike or something Is there any other driver similar to the ones I use right now that can provide much higher currents assuming current rating is the issue?


How do I connect a microcontroller like arduino so that I can have different power levels in the induction coil.

An Introduction to Infineon Gate Drivers www. Martin btw, I am not overly keen on that series of devices configured that way for driving mosfets. Because the gate iir2101 are too big, the switching rise time is very big, therefore the MOSFETs are cross conducting at the same time making a short. Regardless of whether I use 12V or 30V to drive the load, the driver seems to fail when the load draws around 3A.

H-Bridge DC motor driver circuit with IR2101

I need help on how I can implement that circuit for induction cooker project. A gate IR driver is a power amplifier that accepts a low-power input from a controller IC and produces a high-current drive input for the gate of a high-power transistor such as a power MOSFET.

Would ir be a better driver choice for these mosfets? Not sure if the diodes D8 and D9 without a series resistor are OK. If you have any questions concerning our products, please fill out the following form. My tests show that Ohm is “ok” in terms of turn on time. My tests only confirm that higher resistance increases turn on time. Some conflicting advice here.

I’m just curious, considering that I do have deadtime and I’m not currently trying to optimize the throughput yet – does having high resistor values pose any other problems? Martin Don’t remove R17 and R Replacing the driver chips fixes the problem – only until next failure.
