ABSTRACT:
This high frequency voltage generator which may be used particularly in surgery for supplying an electric bistoury, comprises a power oscillator operating an output transformer. A chopping supply is placed in the direct control chain of the power oscillator. The output voltage of the generator is controlled by a first regulation loop whose reference value is increased by means of a positive feedback proportional to the output current.
