1. A method of controlling an electroporation system including a direct current (DC) energy source, a return electrode connected to the DC energy source, and a catheter connected to the DC energy source, the catheter having at least one catheter electrode, the method comprising:
positioning the return electrode near a target location within a body;
positioning the catheter electrode within the body adjacent the target location within the body;
determining a system impedance with the return electrode positioned near the target location and the catheter electrode positioned within the body;
calculating a target impedance based on a combination of a current density threshold and a characteristic of the catheter; and
adjusting the system impedance to calculated target impedance to limit arcing from the catheter electrode.
