      摘 要:隨著新能源汽車的發(fā)展,充電機作為聯(lián)系電動汽車和電網(wǎng)之間的關(guān)鍵設(shè)備,其電磁兼容性能的優(yōu)劣將會影響大充電機的正常工作和電網(wǎng)的穩(wěn)定安全。傳導(dǎo)干擾是電磁干擾的一種重要形式,傳導(dǎo)干擾主要是由開關(guān)管工作過程中形成的過沖電壓產(chǎn)生。本文主要探究通過RC吸收電路減小過沖電壓,從而減小傳導(dǎo)干擾。

      Influence of RC Absorption Circuit on Electromagnetic Conduction Interference in Electric Vehicle Bidirectional Charger Discharge Mode

      Xu Pan Yao Dongwei

      Abstract:With the development of new energy vehicles, as the key equipment between electric vehicles and the power grid, the advantages and disadvantages of the electromagnetic compatibility performance will affect the normal work of the large charger and the stability and safety of the power grid. Conducted interference is an important form of electromagnetic interference. Conducted interference is mainly generated by overshoot voltage formed during switching tube operation. This paper mainly explores the RC absorption circuit to reduce the overshoot voltage, so as to reduce the conducted interference.

      Key words:charger, conducted interference, absorption circuit
