Abstract

The invention discloses an electric automobile smooth capacitor, comprising a main capacitor set, and two leading-out terminals respectively connected to two poles of the main capacitor set; two Y capacitors which are in parallel connection with the main capacitor set after series connection are arranged between the two leading-out terminals; a neutral point leading-out ground terminal is arranged between the two Y capacitors. The main capacitor set is composed of a plurality of capacitor element in parallel connection. The electric automobile smooth capacitor can restrain common mode interference, and has the characteristics of smaller ESR and ESL, and good weather fastness.

Description

technical field [0001] The invention relates to a smoothing capacitor for an electric vehicle, belonging to the technical field of capacitors. Background technique [0002] With the development of pure electric vehicles and hybrid electric vehicles, capacitors for electric vehicles have also been greatly developed. In addition to supercapacitors for storing electric energy, electric vehicles also have smoothing capacitors, whose main purpose is to smooth and filter various irregular harmonics in the electric vehicle power system and improve the operating environment of the power system. In the actual use of smoothing capacitors for electric vehicles in the prior art, there are mainly the following disadvantages: [0003] 1. Unable to suppress common mode interference; [0004] 2. The equivalent series resistance (ie ESR) and equivalent series inductance (ie ESL) are large; [0005] 3. Poor weather resistance, that is, poor high temperature and low temperature resistance, ...
