This invention discloses a high-frequency switching power supply temperature and load joint compensation and lifetime prediction system, specifically relating to the field of high-frequency switching power supply temperature and load technology. By constructing a load-sensitive thermal mapping reference model and introducing temperature rise mismatch characteristics and thermal state vectors, it can identify the spatial partitioning characteristics of internal thermal stress of the chip at different operating stages. This allows the temperature compensation and load adjustment strategies to no longer rely solely on apparent temperature safety judgments, but actively constrain the accumulation rate of local extreme thermal stress, thereby avoiding the problem of latent thermal failure induced even under controlled external temperatures. Simultaneously, it temporally couples the local thermal state with the thermal cycling damage evolution process, updating the damage accumulation and lifetime prediction results in real time after the compensation control is executed. This enables the remaining lifetime assessment to truly reflect the degradation mechanism dominated by local hot spots, significantly reducing the risk of overly optimistic lifetime prediction.
