DC to AC Formula

[Mark82]

Is there a formula used to detirmine how much DC voltage need to convert to a specific AC voltage?

(Example: A generator is putting out XX VDC into an inverter producing XXX VAC)

or is it just a matter of adding a step-up or step-down transformer after the inverter?

If it's three phase then Vdc = 1.35xVac

With modern electronic circuits, this is a product design engineering decision. An DC voltage can be electronically converted to any AC voltage.

While this is true up to a point, economics is the most important factor. It is more expensive and the least efficient to go from lower voltage to a higher voltage.

But still, lots of budget 12V DC to 120V AC units are available. So to some extent it depends on what you got and what you need.

I have picked them up at yard sales for two dollars.
