Design and implementation of driving circuit of mobile robot based on GaN device

This paper discusses the driving circuit design of mobile robot based on gallium nitride (GaN). With the development of science and technology, the mobile robot is widely used, and the performance requirements of the drive circuit are improved. Silicon based circuit is difficult to meet the demand, so gallium nitride is used to optimize BLDC drive circuit. Gallium nitride has the advantages of high electron mobility and high breakdown voltage, which is suitable for high frequency and high power density environment. According to the demand of robot, the drive circuit of gallium nitride is designed to achieve high efficiency and fast response, and improve the performance of robot. Experiments show that the drive circuit improves energy transfer efficiency by 7%, reduces response time by 30:π, reduces energy consumption by 15%, and has excellent thermal management performance. The research results provide a new idea for the design of mobile robot drive circuit and expand the prospect of gallium nitride in industry. In the future, when the technology of gallium nitride is mature and the cost is reduced, the application prospect will be broader.
