Abstract
A method and a system for fault verification of an electronic device are provided. The electronic device includes a device to-be-verified. The method includes the following. A first power-supply voltage is applied to the electronic device until the device to-be-verified satisfies a material-failure condition. A second power-supply voltage is applied to the electronic device to determine whether the electronic device has safety risk. The first power-supply voltage is higher than the second power-supply voltage, and the safety risk is caused by material failure in the device to-be-verified. The method and the system for fault verification of an electronic device can verify safety risk caused by material failure in internal components of the electronic device.
Claims20
A method for fault verification of an electronic device, the electronic device comprising a device to-be-verified, and the method comprising:
- applying a first power-supply voltage to the electronic device until the device to-be-verified satisfies a material-failure condition;
- and
- applying a second power-supply voltage to the electronic device to determine whether the electronic device has safety risk, wherein the first power-supply voltage is higher than the second power-supply voltage, and the safety risk is caused by material failure in the device to-be-verified.
A system for fault verification of an electronic device, comprising:
- an electronic device comprising a device to-be-verified;
- a power supply electrically coupled with the electronic device;
- and
- a controller coupled with the electronic device and the power supply and configured to:
- control the power supply to apply a first power-supply voltage to the electronic device until the device to-be-verified satisfies a material-failure condition;
- and
- control the power supply to apply a second power-supply voltage to the electronic device to determine whether the electronic device has safety risk, wherein the first power-supply voltage is higher than the second power-supply voltage, and the safety risk is caused by material failure in the device to-be-verified.
A non-transitory computer readable storage medium storing programs which, when executed by a computer, are operable with the computer to:
- control a power supply to apply a first power-supply voltage to an electronic device until a device to-be-verified of the electronic device satisfies a material-failure condition;
- and
- control the power supply to apply a second power-supply voltage to the electronic device to determine whether the electronic device has safety risk according to at least one of:
- temperature distribution information, existence of electric arc, or existence of accumulation of electrolyte between a primary coil and a secondary coil of a transformer of the electronic device, wherein
- the first power-supply voltage is higher than the second power-supply voltage, and the safety risk is caused by material failure in the device to-be-verified.
