800VA Pure Sine Wave Inverter's ref. design - If I follow this design 100% same, does it work?

Other Parts Discussed in Thread: SM72295

Hello, I want to ask if I follow the design, does it work 100%? let us say I manage to code the microcontroller properly. and if I want to increase the VA from 800VA to 3000VA, what should I do to the circuit? Just I need to add more FETs ?

thanks alot.

    Which design are  you talking about? Is this a NDA based design?

    Its not as simple as adding FETs lol :)   That too you're increasing the power level to more than 4times.

    You need a Power Electronics Engineer to properly assess the power scale and design the appropriate hardware. Yes, you can very well scale the base model but that too requires an ART and Experience!

    Hello, I am talking about "slaa602" design. The design that use SM72295 as the gate driver.

    How many FETs suit for the design (maximum)? there are 12 FETs in total at TI design of 800VA inverter slaa602.
