Abstract: | A design methodology for the optimal multiple-field-limiting-ring (FLR) termination structure is proposed. In the methodology, a simple modeling structure is developed to find the so-called BV-spacing curve, from which the optimal structure can be obtained directly without trial and error. The results given by the methodology is in excellent agreement with the experimental results. The applicability of the methodology is also investigated in a wide scope, which shows that the methodology has a very good performance in the medium-voltage-range FLR termination design. |
