This article describes a new type of thermal management control and regulation system. This system adopts a "hardware+software" control method, which solves problems such as dry burning and overheating failure of traditional heaters on the market. At the same time, the system innovatively adopts the "IGBT cycling" activation mode, avoiding the risk of thermal failure of a certain path of IGBT due to long-term activation, and can effectively increase the service life of IGBT.
