| Abstract |
The Use of electronics systems at very high temperature (>=200°C) induces important constraints on devices. In this article the consequences of the temperature enhancement on devices are studied in a quasi-resonant power supply. The switch allows soft commutation and is current-bidirectional. The influence of temperature on the complete converter and the implications in the diodes are analysed. This analysIs enables one to define some rules of choice for such applications. With particular precautions, use of classical passive and semiconductor devices is possible above their temperature specifications and the operation of a complete electronics system is feasible at 200°C. |
