Unified detection method for different types of faults, power supply module and storage medium

Abstract

The invention provides a unified detection method for different types of faults, a power supply module and a storage medium. The method comprises the following steps: acquiring to-be-detected operation data, a fault type flag value and a current working state of a power supply module; calculating a difference value between the to-be-detected operation data and a preset detection threshold value corresponding to the current working state; if it is determined that the to-be-detected fault type is not a wait type fault according to the fault type flag value, obtaining a detection difference value according to the fault type flag value and the difference value; determining to-be-detected time according to the detection difference value and a first preset value; and determining whether the working state corresponding to the current power supply module is a normal state or a fault state according to the to-be-detected time and preset detection time corresponding to the current working state. Unified detection of different fault types and different working states can be achieved, the code quantity and the writing process of different types of fault detection are simplified, and meanwhile the problem that the error rate is high possibly caused by the redundant and complex writing process is solved.

Description

technical field [0001] The invention relates to the technical field of power module design, in particular to a unified detection method for different types of faults, a power module and a storage medium. Background technique [0002] With the development of power electronics technology, power modules are more and more widely used in charging piles of charging stations, on-board power supplies of electric vehicles, and power systems. The fault protection mechanism of the power module can make the module work stably when a fault is detected, reduce the failure rate of the module, and realize the self-protection of the module, thereby preventing the occurrence of major accidents. [0003] However, during the process of implementing the present invention, the inventor found that there are many types of faults that need to be detected by the power supply module, including, for example, "over" type faults (such as input overvoltage, output overvoltage, etc.), "under" type faults (...
