Latest Patents

Hwang’s listed patents include inventions focused on improving the performance and manufacture of electronic protection components.

“Multi-layer over-current protector” describes a device made by stacking multiple PTC over-current protection devices with different switching temperatures. Reinforced insulation separates the devices, which are connected in parallel through conducting mechanisms that also serve as the protector’s terminal electrodes. The design aims to reduce initial resistance, increase peak resistance, and improve voltage-withstanding performance.

“Method for preparing composite materials of a positive temperature coefficient thermistor” presents a process for producing a conductive polymer composite using carbon black. The method forms a porous composite electroplating layer on a metal-laminated material, then thermally laminates a conductive, carbon-black-filled polymer composite onto that layer to create the PTC thermistor material.
