ABSTRACT:
The invention provides a novel high-frequency power-supply output control device comprising circuitry for activating push-and-pull operations of a pair of arms of semiconductive inverters comprised of semiconductors being connected to each other in a bridge configuration, in which each arm is alternately turned ON and OFF for converting DC current into high-frequency power, a pair of phase-synchronizing circuits which are respectively installed to these two arms for setting operative frequency of a pair of these arm-forming semiconductors at a specific value, and a phase-difference varying circuit capable of varying the phase difference of these phase-synchronizing circuits before eventually controlling the output high-frequency power ranging from zero to the maximum value being set.
