Greeting All
I am investigating the idea of a Fisher and Paykel wind generator which needs a regulation and grid tie circuit. I have laid out a schematic below and would appreciate some experienced comments on this.
Please no comments of grid tie legality.
The 3 phase AC is converted to DC
The DC is chopped and put through a step up transformer. The chopper also regulates the voltage from the output to maintain a constant voltage?
The transformer output is rectified back to DC
The DC is then converted to mains synchronized AC and injected into the grid. This is not my idea I saw it on http://www.neo-aerodynamic.com/GridTieInverter.html
I would probably use FETs where possible.
run the PWM at a high freq to keep transformer smaller
I am assuming the a slightly higher voltage than mains potential will inject the current. Any ideas of what voltage?
Cheers
Al
