My incomplete memory was of an article 24 years ago in AudioAmateur.I think one of the authors was Jung.I cannot remember how they came up with their numbers but I remember they recommended a minimum of .5V/ÂµS per peak volt of output and a maximum of 2V/ÂµS.The 28V/ÂµS for 100W was figured using their minimum.If we use their maximum we would come up with a figure similar to the numbers your formula produces.All errors are mine.john curl pointed out that I confused rise time with period.For a 500Khz sine wave the voltage would have to rise to the 90* point in .5ÂµS not the 2ÂµS and therefore 2V/ÂµS not .5V/ÂµS would seem to be the minimum.Of course the sine would flatten into a triangle.I don't know where your formula came from but I like it.For 500Khz it reduces to peak voltage*pi so it seems like a magic number :)
