I have seen this exact thing happen in testing when the turns ratio is not right, very poor AC regulation and Duty cycle of 96% at idle. Thanks but there is no display with the original Nano code my inverters run on. Even if there was a display, my geriatric brain might find it difficult to fully grasp the meaning of % of PWM or idle duty cycle . Strangely, this is not the first inverter I built, I have 4 others here (of varying sizes) which do not have that problem. So, you might understand why I am perplexed by this outcome. I shall try phil99's suggestion tomorrow. Meanwhile, today I experimented with another choke and got a slightly better ACV regulation with that, will have to find the best combination for that.
