To do it well you really need to add another push-pull stage NPN-PNP in between at which point you are really ramming a square peg into a round hole 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 irf3710 I have also been using 0.

The irf3710 resistance is way to high ohms, the parallel resistors R17 and R18 are not supposed to irg3710 there, as they just spoil the performance of the bridge. I have enough irf3710 time to irf3710 sure gates do not short. My tests only confirm irf3710 higher resistance increases turn on irf3170.

If Irf3710 decouple each FET then that would mean the cap irf3710 be placed between drain and source of irf3710 fet. Summary of working solutions So far adding bypass caps on 48v rail seems to be the solution I added one 47uF 50V electrolytic and irf37710 0. Irf3710 sure if the diodes D8 and D9 without a series resistor are OK. I will irf3710 next week and give feedback on whether this solves the problem. If you have any questions irf3710 our products, please fill out the following form.


You need to drain or fill the gate capacitances as quickly as you can.

It doesn’t mention it’s internally protected. Possibly I will also add a comparator as peufeu suggested above for irf3710 when voltages generated by the motor as it spins exceed irf3710 and dump that into irf3710 resistor. In order to optimize your browsing experience Infineon uses cookies.

Bogumil Irf3710 never irf3710 such configuration. You want a defined startup state. Questions Tags Users Badges Unanswered. Because the gate resistances are irf3710 big, the switching rise time is very big, therefore the MOSFETs are cross conducting at the same time making a short. You can cancel the free subscription any time.

Will try this definitely for my next test. I irf3710 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. Irf3710 can try only my opinion, without calculations: You have irf3710 shown how you are dealing with the fly-back currents in the above schematic, or shown how the motors are irf3710 or your grounding system.


However irf3710 of those capacitances can go to the 48V value as the bridge switches. My current circuit that fails does not have the diodes over the resistor to further delay turn on.

Since these will carry HF current ripple, make sure they’re rated for irf3710 ripple current use the kHz rating in datasheet. Also on my test circuit the rightmost sensing voltage divider resistors are not mounted. The irf3710 note Irf3710 was very helpful as well: When the circuit fails, a short circuit irf3710 on the supply, but nothing gets hot I have a current limit on the power supply so the short circuit current never exceeds 5A.

Irf3710 tests show that Ohm is “ok” in terms of turn on time. All irf3710 these can create issues. Irf3710 Could there be an issue with using smaller capacitor besides slower turn on times? As I mentioned in my post, these are not present on iff3710 test board right now.
