ABSTRACT:
In a tuned switch mode power supply a zero voltage is maintained across a transistor switch, 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. A modulator of the power supply includes a pair of transistors that form a regenerative switch to produce a portion of a control signal of the transistor switch that causes the transistor switch to turn off. A transformer-coupled input supply voltage maintains the transistor switch conductive as long as the current in the transistor switch does not exceed the threshold level of a regenerative switch. A resonant pulse is transformer-coupled from the resonant circuit to the regenerative switch for turning off the regenerative switch and for maintaining the transistor switch non conductive after the regenerative switch is turned off.
