新型多纤维陶瓷电容器的设计

Design of a novel capacitor: multifiber ceramic capacitor

提出了一种新型多纤维陶瓷电容器(MFC)。MFC由众多纤维电容器并联而成,而每根纤维电容器由内电极(导电纤维)、介电层和外电极构成。理论分析表明,当纤维直径与介电层厚度相匹配时,MFC的电容比多层电容器(MLC)的电容大,而且MFC也具有更优异的抗击穿性能。

Based on the fundamental principles of ceramic capacitor, a new type of capacitor designated as multifiber capacitor (MFC) is proposed. It is made up of fiber capacitors (elements) connected in parallel and bonded together with a binder. Each element consists of fiber core (inner electrode), dielectric coating and outer electrode. Theoretical analysis indicates that MFC has the optimum and greater capacitance in comparison with multilayer capacitor (MLC), when the diameter of fiber core is carefully matched with the thickness of dielectric coating. MFC also has better resistance to dielectric breakdown.
