[0035] Existing technology pre-embeds a PT100 temperature sensor within the auxiliary transformer to prevent it from overheating. While the vehicle is operating, the PT100 monitors the temperature of the transformer coil or core in real time. If the detected temperature exceeds the specified value, the auxiliary converter control unit issues an early warning. However, the lifespan of the auxiliary transformer's PT100 temperature sensor is shorter than the transformer's design lifespan. The PT100 within the coil is embedded during winding, making it difficult to replace. While the PT100 on the core is easily replaceable, there is a significant error between the measured temperature and the hotspot. Therefore, there is still a risk of the coil overheating, shortening the lifespan of the auxiliary transformer.
