When it is less than or equal to the safety calculation threshold, it is determined that the safety calculation evaluation value has hidden dangers and a calculation value danger signal is generated; Identify and judge the calculation qualified signal or the calculation unqualified signal and the calculation value safety signal or the calculation value danger signal: when the calculation qualified signal and the calculation value safety signal are identified at the same time, it is determined that the internal circuit of the induction heating power supply is very safe, and a safe and lossless signal is generated; when any one of the calculation unqualified signal and the calculation value danger signal is identified, it is determined that there is a safety hazard in the internal circuit of the induction heating power supply, and the circuit needs to be repaired, and a hidden danger repair signal is generated; when the calculation unqualified signal and the calculation value danger signal are identified at the same time, it is determined that a fault occurs in the circuit and needs to be replaced immediately, and a damaged replacement signal is generated.
