Snubbing Circuit Realization Based on Numerical Techniques

Abstract

One of the most important and major problems that face the controllable devices for industrial applications, and solid-state switches for pulsed power applications, is the high rate of current and voltage changes during the switching transients of the device. This problem can be overcome by suitable circuitry connected across the device which is well known as a Snubber Circuit. In this paper, a proposed numerical solution using the Fourth Order Runge-Kutta numerical method is applied to evaluate the values of the snubber circuit parameters to maintain the effect of current and voltage rate of changes, during device turn–ON, at levels that the device can withstand. Comparison with other design procedures showed good agreement with reasonable results for the circuit parameters to validate the proposed method.
