Abstract: A high frequency power oscillator is keyed on and off to provide high frequency signal bursts under the control of a pair of timers whose duty cycles are simultaneously and proportionally adjusted so that the signal bursts are constantly centered about the peak power point regardless of variations of the duty cycles. The timers and related circuits for generating control signals are low voltage circuits, whereas the power oscillator is a high voltage circuit, a simple interface structure being provided therebetween.
