Abstract: A power supply device includes a conversion module, a plastic case and an inorganic material, and the conversion module includes an input end, a potential ignition source, a conversion circuit and an output end. The input end is configured to receive an input source, and the potential ignition source is configured to suppress a surge of the input source. The conversion circuit is configured to convert the input source into an output source, and the output end is configured to provide the output source to a load. The plastic case accommodates the conversion module, and the plastic case includes an inner surface. The inorganic material is configured between the potential ignition source and the inner surface, and a distance between the potential ignition source and the inner surface is less than 13 mm.
