Fuse on PiN Silicon Diode Monolithic Integration for New Fail-Safe Power Converters Topologies

Abstract

In this paper, a first concept of monolithic integration of a fuse on a silicon PiN diode is realized and experimentally characterized. An integrated fuse on PiN diode allows fast cut-off, with low I 2 T (less than 2 A 2 .s) and short pre-arcing times (4 to 6 µs). These fuse-on-diode components are intended for failsafe topologies power converter, aiming for more compact and reliable applications. The fuses were electrothermally designed using Comsol Multiphysics™ and TCAD Sentaurus™ simulations were carried out to study their integration on PiN diodes. Characterization and experimental tests were carried out after components realization.
