Abstract
To operate power electronic devices at high ambient temperatures it has to be ensured that the maximum specified junction temperature is not exceeded at any time during operation. This paper presents a method to calculate the actual junction temperature by measuring voltage and current at a power MOSFET during operation of a converter. Based on this temperature, the actual transferred power of a converter can be controlled to ensure a safe operation within the specified temperature limits.
