Description

FIELD The subject matter herein generally relates to vehicle communications. BACKGROUND Electronic equipment such as computers, mobile phones, outdoor wireless base stations, etc., has many functions, requiring high power to meet operation needs. Therefore, a lightning strike standard of the electronic equipment is becoming higher. A lightning protection of the electronic equipment usually comprises a lightning surge protection circuit, a rectifier, and a charging chip, which are arranged in a primary side of a transformer. Among the above mentioned components, the lightning surge protection circuit provides the main lightning protection. The common mode lightning current can flow through the rectifier, the charging chip and a capacitor to the ground wire. The common mode lightning current is related to the value of the capacitor and the lightning voltage. Most of the current rectifiers are discrete Field Effect Transistor or active bridge, which have low current resistance and can be easily pierced when encountering large lightning strikes (above 4 kV). The field effect transistor inside the charging chip also has low current resistance and can easily break by lightning.
