Hi,

I'm looking for a DC-DC converter topology with the following characteristics:

Input Voltage Range 2.7-5V
Output Voltage: 12V
Output Power: 1kW

It is not of primary importance the isolation.

Do you have any suggestions about the most suitable DC-DC converter topology (high power and high gain) ?

Thank you in advance.

 

Hello,

1kW is a lot of power.
At 12 Volts it would mean a current of 83.33 Amp.
At the input of 2.7 Volts it would mean a current of about 400 Amp.
What would be in input source?
How long would the 1 kW be mentained?

Push-Pull into a Toroidal-Transformer the size of your Car.
No kidding .........

BTW, where did You find a 5V Battery that can sustain 400-Amps for more than a few seconds ?

You'd find a couple of dozen of them in a fork-lift truck.
