1. In an electrosurge generator energized by a power supply, and producing an output voltage of a desired level, an improvement comprisinga failsafe circuit for preventing an excessive high output voltage from the electrosurge generator resulting from a failure therein,said failsafe circuit including voltage detection means coupled in parallel across the voltage output of the electrosurge generator for detecting an excessive high output voltage of at least a predetermined threshold, anda switching circuit means activated by said detection means and connected in parallel across the power supply for short circuiting the power supply without diverting the output current to flow therethrough, thereby removing the power supplied from the power supply to the electrosurge generator.
