Introduction to the difference between active and reactive power in AC circuits
In an AC circuit, there are two types of electrical power supplied to the load from the power supply: one is active power and the other is reactive power. When the load is resistive load, the power consumed is active power, when the load is capacitive or inductive load, the consumption is reactiv...Read more -
Analysis of film capacitors instead of electrolytic capacitors in DC-Link capacitors（2）
This week we continue with last week’s article. 1.2 Electrolytic capacitors The dielectric used in electrolytic capacitors is aluminum oxide formed by corrosion of aluminum, with a dielectric constant of 8 to 8.5 and a working dielectric strength of about 0.07V/A (1µm=10000A). However, it...Read more
