Failure Rate Examination for Liability Tree-Based Analysis for Clamped Double Subsystem With DC Short Voltage Protective Functionality

Abstract

This study presents a comprehensive failure rate examination for implantable antennas, employing a liability tree-based analysis focused on a clamped double subsystem (CDSM) equipped with DC short voltage protective functionality. The enhanced protective feature of the CDSM aims to improve the security and safety of implantable antennas used in critical applications. However, this subsystem's design necessitates the use of additional IGBTs, diodes, and capacitors compared to standard configurations, consequently increasing the complexity and potential failure rate. Given that demanding converter operation in implantable antennas can escalate the failure rate, conducting a precise reliability analysis becomes vital for the deployment of CDSM in these devices. A failure durability analysis is undertaken to address the operational characteristics of CDSM in implantable antennas. Fault Tree Analysis (FTA) is utilized to evaluate the risk with greater precision than previous methods, which mainly considered component types, quantities, and network connectivity states.
