摘要
针对现有电动伺服系统驱动电路效率低、电路复杂、强弱电不隔离等问题,介绍了一种输出电流达36 A的直流有刷电机功率驱动电路,该电路具有效率高、热功耗小、与微控制电路光电隔离、单电源供电等优点。将该电路分解为四个组成部分,对各部分详细说明,并从整个电路内部工作原理及仿真实验情况作具体分析。
Aiming at the problems such as low efficiency,complex circuit and non-isolation of strong and weak electricity in existing electric servo system,a DC-brushed motor power drive circuit with output current of 36 A is introduced in this paper.This circuit has the advantages of high efficiency,low thermal power consumption,photoelectric isolation from micro control circuit,single power supply and so on.In this paper,the circuit is decomposed into four components,and each part is explained in detail.The concrete analysis is made from the working principle of the whole circuit and the simulation experiment.
