AI Technical Summary
When the charging module is distorted, safety problems such as fire on the input side differential mode capacitors and damage to the rectifier diode are prone to occur. Moreover, the grid environment of charging piles in different places is different. How to improve the adaptability of the charging module to the power grid has become an urgent problem.
A method for input overcurrent protection of the rectifier module is proposed. By continuously obtaining the input current of the rectifier module, overcurrent protection is performed when the preset response time is reached and the input current is within the preset overcurrent protection range. The method includes various strategies such as outputting modulated waves through the current loop controller, fast wave sealing through software triggering, and fast wave sealing through hardware overcurrent protection signals.
By adapting to the input current of the rectifier module in real time, the charging module's adaptability to the power grid is improved, the safety and reliability of the charging module is ensured, and safety problems caused by grid distortion are avoided.
