Roger, to give you a ball park figure of how much idling power a finished inverter, using the 3KW aerosharp core re wound, uses:
I have just completed re doing the complete electronics for this inverter, it now uses Poida's nano with opto isolated totem pole drivers as per wiseguy's design.
The total idle power, including core magnetising current and all the electronics, is 17W at 55V battery voltage.
Funnily enough, the original idling power with the EG8010/ IR2110/ totem pole arrangement as per madness design, but with identical transformer as above, took 29W all up to run.
So, something to consider down the track if you are concerned about idle power.
I'm re doing my warpverter boards to use totem pole drivers, they seem to be much better in handling paralleled mosfets than straight off the FOD3812 drivers as per warps schematic. |
