DC voltage level reduction

[Buzaina Moossa]

Hi all,

I am facing a problem of DC voltage level conversion.The DC bus voltage available is 250-680V.
How can I convert it to a range suitable for charging a 24V battery.

Is it possible to input this DC voltage level to a standard SMPS which converts AC to DC for example, 90-265V AC converted to 36.

Can anyone share their thoughts on this?

Waiting for response..

Thanks and Regards

680v is way high for such an application better do it with half bridge.

I think he mean on 380V.
