Boost Converter(Vin=24/48v, Vout=220v, Iout=1.8A)

[CaptiveMuhammad]

Thanks in Advance.. Please Help ..
My FYP is about "Driving 3-Phase Load using Solar Panels"
I am Using Boost Converter to Convert it to 230 volt and Then will Use 3-phase Inverter..
:roll:

Since your step-up ratio is large, have you considered a full H-bridge driving a transformer?

Or possibly 3 transformers, since you want 3 phase?

If you absolutely want to do it with boost converter topology, it will require that you provide 24V at 20-25 A. At such current levels it is worth it to consider interleaving 2 or more boost converters. In your case 3 boost converters, since you want 3 phase.

Paralleling two simple boost converters with 500W power rating would be enough, then you can connect both outputs to your DClink. Since your current is quite high as well as your output voltage, current and voltage stress of your switch will be quite high. You will need, at least, a dissipative snubber circuit.

Take into account that with a simple boost converter you will need to use duty cycle around 90%. I would study the possibility of using an isolated topology as the full-bridge.
