ABSTRACT:
In a tuned switch mode power supply a zero voltage is maintained across a transistor switch, during both turn off and turn of switching transition intervals in the transistor switch. The tuned switch mode power supply operates in a current-mode control, on a current pulse-by-current pulse control basis. An over-current protection circuit disables the transistor switch when an over-current condition persist longer than a first interval that is substantially longer than a period of a given current pulse in the transistor switch. The operation of the transistor switch is undisturbed, when the over-current condition lasts only a shorter interval than the first interval.
