I’m working on a wearable battery project and I think it’s best to use AC power for the voltage and current adjustments, as well as stable transmission over long distances. Because it’s battery powered it needs to be as low energy as possible.
For that reason, I was wondering if it was possible to have the inverter be “always on” but only draw the amount of power needed to run the connected devices. Furthermore, I imagine the inverter itself would draw some power, so I assume it would need to draw power to run itself only when a device is drawing power. Would anything to that effect be possible?
I’m picturing an arrangement wherein a device, for example a fluorescent light tube (I won’t be using one for the project but it’s a common AC load device), would be connected to the inverter output directly. The circuit suddenly becoming closed would allow current to flow and the inverter would begin to operate normally. This would happen without drawing a fixed current, but rather just enough to run the light and the inverter. Ideally all of that would happen without digital logic components being involved.
