Patent KR-20010106312-A (KR)
Inventor: JUNG HUN JAE
Filed: 2001-09-25
Abstract: In a tuned switch mode power supply a zero voltage is maintained across a transistor switch (Q3), during both turn off and turn on 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 (200) disables the transistor switch when an over-current condition persists 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.
