A bipolar Marx generator for a mobile electroporation device

Since 2000 a mobile electroporation device has been operated for scientific and testing purposes. Now a breakdown of the insulation at one Marx generator output to ground has occurred due to an electric overstressing. This failure makes a redesign of the Marx generator necessary. For the redesign a bipolar Marx generator with a transient insulation to ground has been compared to one with a fixed center ground connection. The paper describes why the solution with the fixed ground connection is considered to be more suitable for the application in the mobile electroporation device.
