Hopefully? Another 48vdc-240vac Toriod Inverter build.

They say the Choke is for a Transformer design Inverter, but the choke looks more like a Transformer-less Inverter choke, DC->HVDC->AC. It appears to have 4 Toriod rings and is similar to the windings of Chokes in these Inverters and they also have a much higher Inductance. The toriod Choke I purchased some time ago has around 6 in hand heavy gauge wires, they are wound as a single layer winding, there is no twisting on the cores, no lumping, no overlap, completely flat side by side with some spacing that does not quite fill the full circumference of the toriod rings. Strange, unless the one you have uses very small toriods? . I did some more reverse engineering and found out that it has 9 turns 10-in-hand (strands) of 2mm dia. copper magnet wire. There are 3 toroid rings that is probably this. Edited 2023-06-01 11:07 by tinyt
