design a dc electronic load and feedback energy to ac line

[mag]

I want to design a dc electronic load and feedback test unit energy to AC line. I use BOOST circuit to conveter dc output into hign dc voltage,then use inverter circuit feedback to AC line. But I don't know how to program the test current?

anyone can send me some suggest? thanks a lot!

Re: design a dc electronic load and feedback energy to ac li

when you use inverter circuit feedback to AC line, the load of DC is nothing, since it parallels supply power with mains. In this way, you can't control the load. You have to burn that energy to heat or something else. That is electronic load.

But use for a electronic load ,it is need current controling.I think use a pre-module to control current ,then input to inverter circuit.
but how can i design this pre-module and only product little heat?
