Gate Driver and PCB Layout in DC / DC Full Bridge Converter

[azadfalah]

Hi friends I hope you are great


I am designing a full bridge dc / dc converter, please comment on my PCB Layout and Gate Driver

Topology : Full Bridge
Frequency = 50khz
Input : 24V
MAX Input Current: 50A
Output = 350V DC
Power = 1KW
Gate Driver : IR2113

In the previous design, i had a problem with the Vgs Rings
After researching and fixing the bugs, this design is finalized, Please guide me to make it better

*The primary transformer wires are connected directly to the heatsinks

Thanks

Highlight all switching node nets and then see if they impinge on sensitive traces, eg traces going into High Z inputs on the controller IC etc.

Hard to decode the actual layout, we need a kind of transparent layer display. What is it, 2 or 4 layer, 1 to 4 oz? If not thick copper or multi layer, I doubt it can stand 50 A. A schematic of the driver circuit would be also helpful.

You have a computed gate drive R ?
