ABSTRACT:
An autocontrol circuit for a resonance current or voltage undulator comprising a power supply, a parallel or series resonant circuit connected to the supply, and circuit elements (K.sub.1 to K.sub.4) for reversing the polarity of the resonant circuit's connection to the power supply. The power supply comprises a DC voltage generator and an inductive or capacitive element (2). The autocontrol circuit comprises circuit elements for detecting the voltages or currents of both the DC voltage generator and the output of the power supply. Differences between these two measured quantities are related to the load variations of the resonant circuit. The autocontrol circuit also comprises a comparator (11) for determining these differences, and circuit elements to use the comparator's output to produce signals which control switches (K.sub.1 to K.sub.4) which determine the polarity of the resonant circuit's connection to the power supply.
