• In this paper we analyzed the existing schemes of high-voltage generators, which can be used in electric pulse drilling for finding the most optimal design. To determine the criteria that such a generator should meet, a detailed review of existing electric pulse drilling technologies was carried out. It showed that downhole generator is most effective way for drilling deep wells. The creation of such type generator is greatly hampered by many factors. By analyzing these factors, we have formulated the basic requirements for high-voltage generator. After comparing the strengths and weaknesses of existing oscillator circuits, the downhole generator optimal design was chosen.
