L6565 quasi-resonant controller
... Another important benefit is a high safety degree under short circuit conditions: since the conduction cycles of the MOSFET are inhibited until the transformer is fully demagnetized, flux runaway and, therefore, transformer saturation are not possible. Moreover, as during a short circuit the demagne ...

... relaxation times appear to range between 10 ' and 10' seconds. Perhaps it seems remarkable at first that times so long should be associated with any atomic process. On the contrary, such times were, from the theoretical point of view, unexpectedly short, for the processes which had been examined the ...
