Abstract
An electrosurge generator, which is energized by a power supply to produce n output voltage of a desired level, includes a failsafe system at its output to prevent any excessive high DC voltage output which may result from a failure in the electrosurge generator. The failsafe system has a detection element coupled to the output of the electrosurge generator which detects any output above a predetermined threshold. A switching circuit is activated by the detection element. The switching circuit is connected across the power supply, and when activated, removes the power supplied from the power supply to the electrosurge generator.
