Frequency controlled resonant inverter

摘要

A high-frequency high-voltage generator is provided for x-ray technology that automatically adapts to all load instances and to the coupling network. The inverter is driven dependent on the zero-axis crossing in a series resonant circuit. The capacitor of this series resonant circuit is bridged by an inductance, forming a parallel branch and the control signal for the inverter is acquired from the time delay between the zero-axis crossings in the series resonant circuit in the parallel branch.
