Part Number: TIDA-00917 I was going through the TIDA-00917 design document. In page no. 6 there is one zener based split supply circuit. I was wondering whether the same zener based arrangement can be used in inverter circuits with common supply (i.e.…
Part Number: TIDA-00917 Other Parts Discussed in Thread: UCC21732 hi, TI support
The reference design TIDA-00917 seems to be very helpful.
May I ask the following questions:
1) how to size the CM choke used for IGBT gate drivers to drive multiple IGBTs…
Part Number: TIDA-00917 hi TI support
Could you explain the benefits of adding a 0.22uF cap between GATE and EMITTER of each IGBT?
as shown below.
This would increase the driving power loss, and slow down the turn-on and turn-off transition.
Please give…
Part Number: TIDA-00917 Hello Guys,
Good day.
The TIDA-00917 was d esigned to Drive Parallel I GBT Modules. But there are different IGBT modules and our customer would like to know what specific module type was used?
His concern is that the lead inductance…
Part Number: TIDA-00917 Looking at the nice IGBT gate driver you implemented in TIDA-00917 I think it will be too expensive having 4 dc dc converters to supply gate drive voltages. Is there a way to implement it using bootstrap capacitors and still get…
Part Number: TIDA-00917 Hi everyone
good day!
one thing that really shocked me is ,how electro magnetic field does not effect on gate drive board?!!!
the first question that comes to my mind is 900Ampers /700volt IGBT switches around 10 KHZ generate enormous…
Part Number: TIDA-00917
Hi Team,
I have two questions:
1. Can I have to know how to calculate the CM inductance value in this schematic? Based on what?
2. I noted Infineon has been released a IGBT/MOSFET driver which is constant current type, the link…
Part Number: TIDA-00917 How much Lg will CM choke introduce to the gate loop?
The design BOM shows the part number is B82789C0/S0. According to that, Lr of 11uH shows Lstray,typ of 60nH. Does that mean the introduced Lg is 60nH?
