THe transformer's peak power (or current) draw is what causes a transformer to saturate right? Not the average power?
The transformers I am looking at for the ultrasonic driver are 1/4W transformers and no other information is realy given to help figure out saturation other than that they can handle a maximum of 250mA DC. THe transformer will need to output a peak 200Vp@62.5mA = 12.5W. Now the transformer has an input of 12Vp and efficiency of 50% with 16:1 ratio so the peak input power would be like 24W.
THe average power however works out to be 0.2W output or 0.4W input, near the power rating of the transformer and I can reduce the duty cycle by 10 to greatly reduce average power. But since the peak ratings are so far beyond what the transformer is rated for it would probably still saturate right? Regardless of how much I lower the duty cycle to reduce the average power since the peak powers still stay the same (I can't do anything about those).
