Programmable regulating non-polar capacitor based on high dielectric material

Abstract

The invention discloses a programmable regulating non-polar capacitor based on a high dielectric material. The capacitor comprises a parallel plate capacitor and a programmable logic controller, wherein the parallel plate capacitor consists of a lower electrode plate, at least two upper electrode plates with different areas and a high dielectric material filling layer; an outgoing line of each upper electrode plate is connected with a main terminal of a bidirectional thyristor; the other main terminal of the bidirectional thyristor is a common terminal electrode; the main terminals of the bidirectional thyristor are connected with each other to serve as a wiring terminal of the parallel plate capacitor; a lower electrode led out of the lower electrode plate serves as another wiring terminal of the parallel plate capacitor; a control signal output port of the programmable logic controller is connected with a gate pole of the bidirectional thyristor through a drive circuit; and the highdielectric material filling layer has the relative dielectric constant of more than 100,000 and the thickness of less than 0.3mm. A capacity value of the capacitor can be adjusted through a system programming method, and the capacitor has the characteristics of small volume and high capacity, is convenient to adjust and is suitable for the fields of various electronic products in which capacity values in circuits are needed to be adjusted in real time.

Description

technical field [0001] The invention relates to a non-polar capacitor, in particular to a programmable adjustable non-polar capacitor based on high dielectric material which can adjust the capacitance value through in-system programming. Background technique [0002] There are two types of existing capacitors: polarized capacitors and non-polarized capacitors. Polarized capacitors are mainly used for power supply and filtering, and the usage is limited. Non-polar capacitors are used in a large amount in the modern era of miniaturization and high intelligence requirements of electronic products, and they have good electromagnetic compatibility, reliability and safety, so their application prospects are very broad. For different modern intelligent electronic products, we need to use capacitors of different types and specifications. When using them, we must pay attention to many parameter requirements and different capacities. Not only is it inconvenient to use, but it also ca...
