Procedimiento Novedoso para el Diseño del Circuito Amortiguador RCD (Snubber RCD) y Deducción Matemática de las Ecuaciones.

This paper proposes a new procedure for the design of snubber RCD in power electronic circuits to reduce the peak transient voltage when the power switch is turned off. The procedure involves a method for the determination of parasitic elements in the switching circuit and the mathematical deduction of design equations. The proposed procedure is a useful tool for the analysis and design of snubber RCD circuits, used in the majority of power electronic circuits. The design equations obtained in this work allow the theoretical calculation of the value of the capacitor and of the resistance of the snubber RCD based on the parasitic reactances of the implemented circuit and the maximum operating voltage of the switch, allowing the verification through simulation of the dynamic performance of the circuit before the experimental implementation. The procedure and the design equations are verified in the laboratory, corroborating the consistency of the theoretical analysis with the experimental results. [ABSTRACT FROM AUTHOR]
