Abstract

U ovome radu definiran je okoliš s visokom temperaturom kao okolina na kojoj je temperatura veća ili jednaka 180 C. Dan je pregled temperaturnih degradacijskih mehanizama električnih komponenti. Razmotren je utjecaj visokih temperatura na ostale dijelove ugradbenih sustava kao što su tiskane pločice, kućišta električnih komponenti, žica i materijala za povezivanje električnih komponenti s tiskanim pločicama. Dan je pregled trenutnog stanja visokotemperaturne poluvodičke tehnologije (SOI, wide bandgap poluvodiči). Napravljen je pregled tipičnih visokotemperaturnih komponenti koje se mogu nabaviti na tržištu (COTS). Tipične komponente koje se mogu nabaviti na tržištu možemo svrstati u sljedeće grupe: operacijska i instrumentacijska pojačala, mikrokontroleri i DSP, oscilatori, AD pretvornici i naponske reference te linearna i prekidačka napajanja. Dan je pregled pogodnih vrsta pasivnih komponenti za okoliš s visokom temperaturom i navedene su njihove prednosti i mane. U sklopu rada osmišljen je jednostavan senzorski ugradbeni sustav za nerazorna induktivna mjerenja u okolišu s visokom temperaturom koji koristi COTS komponente.

Abstract (english)

In this paper, environment with high temperature is defined as environment where the ambient temperature is greater than 180 °C. An overview of the temperature degradation mechanisms of electrical components is given. The influence of high temperatures on other parts of the embedded systems are considered (printed circuit boards, electrical component packaging, wires and electrical components interconnects). An overview of the current state of high-temperature semiconductor technology is given (SOI, wide bandgap semiconductors). An overview of high-temperature commercial of the shelf (COTS) signal chain components is given. High temperature COTS components typical for signal chain can be classified into the following groups: operating and instrumentation amplifiers, microcontrollers (and DSPs), oscillators, AD/DA converters, voltage references, linear and switching power supplies. A review of suitable types of passive components for environment with high temperature is given with their advantages and disadvantages listed. An embedded system for non-destructive inductive measurements in the high temperature environment using COTS components has been designed.
