DC-SSCB Snubber for Electric Propulsion Ships With Effective Surge Voltage Reduction and Fast Dissipation of Fault Current Energy

open access: yesIEEE Access
This paper proposes a snubber circuit for SSCB that performs voltage clamping operation in two stages to reduce surge voltage. The surge voltage is suppressed in the first stage using a MOV with low operating initiation and clamping voltages.

Estudio comparativo de dos métodos de síntesis para la obtención de polvos cerámicos de ZnO - Pr2O3 - CoO

open access: yesBoletín de la Sociedad Española de Cerámica y Vidrio, 2004
Zinc oxide containing rare earth metal and Cobalt oxide are utilized as raw material to make varistors. Some of systems were found to exhibit non-ohmic current-voltaje characteristics and they are applicable not only for low voltaje devices but also for ...
