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

Its the ATS switching the LOADS over to the Inverter, that's a 62A peak DC pulse, not much but obviously the change over is not synced so anything could happen playing Russian roulette, but no blowups with the inverter, Toriod doesn't even grunt at me. Seems like the AC distortion is not causing any real current or instability issues with the toriod or inverter, switched loads don't seem to care much.   EDIT: You know, that AC spike and ripples on the following leading slope look like the result of a brief muted ringing in the toriod. Below: Inverter Halt [off]. Triggered by SPWMEN enable disable. Wondering if I should fit the all the extra diodes across the FETS, just in case. For someone new, Blue is Inverter AC out and Yellow is the trigger point on the SPWMEN line to the 8010 when the drive waveforms are disabled at power off. . Edited 2023-05-27 18:06 by KeepIS
