Title: Innovations by Cheng-Yu Tung
Introduction
Cheng-Yu Tung is a notable inventor based in Tainan, Taiwan. He has made significant contributions to the field of circuit protection devices, holding a total of five patents. His work focuses on enhancing the safety and efficiency of electrical systems.
Latest Patents
One of his latest patents is a circuit protection device that includes a first temperature sensitive resistor, a second temperature sensitive resistor, an electrically insulating multilayer, a first and second electrode layer, and at least one external electrode. The first temperature sensitive resistor and the second temperature sensitive resistor are electrically connected in parallel, featuring a first upper electrically conductive layer and a second lower electrically conductive layer, respectively. The electrically insulating multilayer consists of an upper insulating layer, a middle insulating layer, and a lower insulating layer. The upper insulating layer is positioned between the first upper electrically conductive layer and the first electrode layer. The middle layer is laminated between the first temperature sensitive resistor and the second temperature sensitive resistor. The lower insulating layer is situated between the second lower electrically conductive layer and the second electrode layer. The external electrode is placed on the first electrode layer and extends beyond a peripheral wall along a horizontal direction.
Another significant invention is an over-current protection device that comprises first and second electrode layers with a PTC material layer laminated in between. The PTC material layer consists of a polymer matrix, a conductive filler, and a titanium-containing inner filler. The polymer matrix is made from a fluorine-free polyolefin-based polymer. The titanium-containing inner filler is represented by a compound with the general formula MTiO, where M signifies a transition metal or alkaline earth metal. The total volume of the PTC material layer is calculated as 100%, with the titanium-containing inner filler accounting for 1-9% by volume of the PTC material layer.
