1. Composition and structure of filter and parallel capacitors device 🍏The AC filter consists of high and low voltage capacitor banks (capacitor towers), reactors, resistors, lightning arresters, current transformers (oil-filled, [...]
🍏The configuration of AC and DC capacitor filters in the converter station is mainly based on the harmonic components and reactive power requirements of the AC and DC sides of [...]
Let's go through this chapter to understand the role of the lower parallel capacitor device and the harm of harmonics. 🌈Usually DC transmission converter stations are divided into DC area [...]
1 Temperature characteristics of capacitance 🍏Are the parameters of aluminum electrolytic capacitors affected by the application environment?Capacitance varies with temperature. The change itself is determined by the rated voltage and [...]
1.1 Overview 😋Electrolytic capacitors should be called electrolytic capacitors because one of the electrical stages of such capacitors is not a metal but an electrolyte or metal oxide. In short, [...]
1.Overview 🐾Mica is an extremely important and excellent inorganic insulating material. As a dielectric material, it has not yet been found that the comprehensive properties of other materials can exceed [...]
1 Application of large-capacity ceramic capacitors in general bypass 1.1 The role of bypass capacitors 🍏Bypass capacitors are usually connected in parallel across the power supply of a circuit unit [...]
🌻An electrolytic capacitor differs significantly from other types in that its dielectric is an extremely thin anodic oxide film electrolytically generated on the valve metal, the thickness of which is [...]
🍉Different from other chip components, use of multilayer ceramic capacitors may be damaged due to large stress due to the thin internal electrodes and dielectrics, and the dielectric is very [...]
