At 18:00 on the evening of September 2, the 17th session of the Changsha Jianke Electronics Co., Ltd. Technical Forum on the abnormal temperature rise of electronic fans was successfully held in the training room on the 5th floor of the R&D building. The software engineer Su Siqi served as the training lecturer. , A total of 10 people from the company’s technical department and sales department participated in this training, including 9 from the technical department and 1 from the sales department. Through this training, let everyone know that the temperature rise of the fan controller components is one of the key factors for the safe and reliable operation of the fan, and the temperature rise of the MOS tube is the most important reason. Through this training, I hope everyone can understand the impact of the dead time setting on the temperature rise of the MOS tube, especially when the current increases, the MOS tube will be turned off and there will be a tail, and the dead time setting must be more accurate.
