[0002] With the advancement of industrial technology, the proportion of induction heating power supplies used in various fields is increasing, and at the same time, higher requirements are placed on the power density of induction heating power supplies and the versatility of the system. Since the induction heating power supply uses the principle of eddy current heating generated by high-frequency current, the electrical components in the system generate a lot of heat, and real-time monitoring, adjustment, and efficient feedback of the water system are particularly important. For water-cooled core components, after the system stops running, the long-term storage of cooling water in the system will increase the risk of damage. The traditional system drainage method is inefficient, labor-intensive, and has the risk of omissions.

[0003] In order to solve the above technical problems, a multifunctional induction heating power supply water cooling monitoring system and method are proposed. Summary of the invention
