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.
