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

The DC input current peaks reach 550A, around 15A less then with the 45uH choke, but can't really rely on that as so many environmental and physical conditions can effect that. Once Again when I examine the full images, there is no longer any ringing in random AC cycles. The variation in DC Cycles is almost nonexistent. The startup is much cleaner with almost no ringing as the load is dropped onto the inverter.   When I get a chance I'll post a capture of the 46uH choke introducing random ringing in to the AC, that has gone in all of the 40uH captures. .
