Original poster: "Godfrey Loudner" <ggreen-at-gwtc-dot-net> Hello Dan Comment interspersed below. Godfrey Loudner -----Original Message----- From: Tesla list [mailto:tesla-at-pupman-dot-com] Sent: Thursday, June 03, 2004 5:32 PM To: tesla-at-pupman-dot-com Subject: Modeling E-Fields of Tesla Coil - Building a model Original poster: "Eastern Voltage Research Corporation" <dhmccauley-at-easternvoltageresearch-dot-com> I have ANSOFT's Maxwell 2D and 3D program which can do both magnetostatic and electrostatic modeling. Just had a few questions for how to properly model a tesla coil. The work of Paul suggest that the voltage rise along the secondary is somewhere between linear and sine. This is far from a complete answer. But make your assumption and see what happens. SECONDARY COIL ***************** Can I make the assumption that voltage is evenly distributed down the secondary coil from the potential seen on the top load to the ground plane (0V)? If so, I would probably split the secondary into a number of smaller disks and assign a potential for each disk. FOR SINGLE TOROID ******************* For a single toroid, i assume the entire toroid should be set at a single voltage. A charge placed on a toroid will distribute itself so that the potential is the same at every point of the surface. FOR DOUBLE STACK TOROIDS **************************** How do you treat the potential across say two stacked toroids. Do you assume each toroid has equal potential ? ? ? Same as for a single toroid. BREAK-OUT POINTS ******************* Should be easy enough by merely putting a small dib on the toroid. The electric field will be more intense at a pointed portion of a surface. Any other thoughts or comments?? The simulator might work if you can input the correct distributions, but what might they be? Thanks Dan
