UCC14131-Q1: 1500V Isolated DC/DC modules

Martin Fertmann

Part Number: UCC14131-Q1

Hello,

is it planned to release the UCC14131 or similar Isolated DC/DC modules for a working voltage of 1500V (8 kV surge isolation voltage; Basic Isoltaion rating)?

Many thanks in advance.

Hi,

Can the current UCC14131-Q1 meet your specs? If not can you point out which below?

At moment, we still need to gather information to see which new devices to release.

Hi,

The maximum working insulation voltage would have to be increased to 1500VDC and the maximum impulse voltage (Tested in air, 1.2/50-μs) would have to be increased to 8kV.
I interpret this according to DIN EN 62477-1, which in turn is based on 60664-1.

Hi,

the surge 10kV seems ok for your design. So the shy is 1414VDC compared to 1500VDC, right?

Please confirm then I can provide such to the design team for their information gathering. What application is this and why 1414VDC not working for you?

Yes, the shy is 1414VDC compared to 1500VDC.
The application is a gate voltage supply for SiC modules at up to 1500V continuous DC link voltage.
The gate-transformer must generate a basic insulation (against PE, OV3).

I would prefer a gate power of 2W, but 1.5W would also be ok.

Hi,

Ok, I will let the design team know. Please check back in two weeks to see if there are plans or any other suggestions for your need.

Hi,

I talked to the design team. The team wants to understand your application more. Please send to me through email for this need so I can connect you to our design team.
