摘　　要：针对传统井径仪电机驱动电路功耗大、操作复杂等问题,设计了基于IR2110的高压侧悬浮驱动自举式H桥电机驱动电路。本文优化了自举元器件以及设计IR2110的相关保护电路,提高电路的稳定性;优化了电机驱动负载运动位置的控制方式。实验结果表明,采用IR2110组成的H桥驱动电路,可以完成对井下电机启动、正转、反转和停止等工作方式的有效控制,并具有接口隔离和运行稳定、可靠等特点。Aiming at the problems of high power consumption and complicated operation of the motor drive circuit of traditional caliper,a high voltage side hover-driven H-bridge motor drive circuit based on IR2110 was designed.This article optimizes the bootstrap components and designs the IR2110-related protection circuit to improve the stability of the circuit.The control mode of the motor-driven load motion position was also optimized.The experimental results demonstrated that the H-bridge driver circuit composed of IR2110 can effectively control the startup,forward rotation,reverse rotation and the stop of downhole motors,and have the features of interface isolation,stable and reliable operation.
