摘要：
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.
