Low cost DC-DC converter/SMPS design idea and suitable topologies

[Md Mubdiul Hasan]

Hi there,

I am looking for a customized design where good power solution can be applicable.

My aim is to develop a DC-DC sutable toloplogy ( flyback, buck, isolated ,..so on) converter with following parameter, with the idea https://www.smps.us/topologies.html

INPUT: 250 to 650 VDC

OUTPUT: 24V/5A , 5V/3A, 12V/2A.

Lets think its saparate system for all output. Offcourse this design is challenging since it has wide range of input.

 Its for battery charger or EV application.
