Hello,
I'm developing a Firmware in order to control a Triac at high votage side of the transformer with a charging tap .
In my case is a 90vac tap Relay switched when Mains are present. Transformer high voltage side is (Neutral,90vac and 120vac). In tention is use Body Diode of Mosfets as full wave rectifier.
Control board will follow votage 3 stage profile depending on voltage selected ( of course battery and transformer must match)
Before switch to "charging" state when mains are present , I'm asured that Inverter is powered down ( using SD) .
Questions :
1-There is a 20k resistor across Gate/source on OzInverter ... When shut down this resistor would be held the mosfet at the ground potential ?
2-The feedback Transformer which connected VFB , May use a 0.5 VA 14vac ? I want to incorporate a smallest transformer there .
Any comment/suggestion would be highly Apreciated
