Communications can be disrupted by high data error in high power converters especially in strong electromagnetic environments.This paper describes the system structure and data types of a controller area network(CAN) for a high power converter.The critical points in the software design were analyzed and the procedure flows were optimized to guarantee the efficient,timely and reliable transmissions in the communication system. Test results validated the stability and reliability of the optimized system without any communications halting and data missing even with serious interference.The system data error and failure rates are significantly decreased,which indicates the feasibility of the optimized design.
