I am evaluating three converter topology design, one is a simple flyback circuit, the other one is an interleaved flyback, and lastly the active clamp flyback? all these three provides better responses for an inverter circuit, which one would be best?
 

Electronic circuit design ALWAYS involves a tradeoff between different and often conflicting requirements.
Mostly: size, cost, complexity, performance and reliability. And depending where in the world you live, component availability.

Performance can be subdivided into efficiency, noise, component stresses, and such.

My personal philosophy is to always use the simplest circuit that will meet my performance requirements. Which in most cases, is the simple flyback.

Auxiliary Power supply - Inverter

Do I really need to put a transformer on my auxiliary power supply? my input and output voltage are both dc anyway. I just saw an auxiliary power supply for an inverter and it uses a transformer, and dedicated winding for each Power supply, what is the transformer for?

Hi Dann !
Sorry but i'm not ray charles or oracle ! please show a schematic or something that could clear your aim out ! what kind of power supply ? what kind of aux ?
in what kind of system . when you say PSu , it refers to a lot of subjects .
With these low information i just can say transformer in power supplies is being used in order to some reasons , one of em is energy transforming ( increasing voltage or current or vice versa ) changing impedances ! creating isolation ! or ...


For more help deliver more information

To step up DC to DC without a transformer, there is the boost converter, buck-boost, sepic. These are inductor based.

Also capacitor-based voltage multipliers.
 

Yes, we need at least…

Vin =
Vout =
Pout =
Continuous max load or just transient?
Need for small size?
 

Yes topology depends on max continuous power you want to process....
