Design and analysis of the Tesla transformer with duplex secondary winding

A Tesla transformer with duplex winding is designed. The secondary winding of the transformer is divided into two parts, a 120-turn tapered winding and a 6-turn extra winding, which combine the transient oscillation of the main tapered winding and the main gap's trigger electrode. This configuration improves the performance of the main gap and makes the generator more compact. Two types of numerical techniques are introduced: a time-dependent finite element method model and a double transmission line lumped circuit model. To validate these models, calculated voltage signals on the extra winding are compared with the measured signal. The verification test shows that results of the two models are acceptable. Errors between the measured signal and simulation results are explained.
