摘要
介绍了电流-电压转换器片MAX472的功能及工作原理,详细介绍了MAX472在异步电机软起动控制系统中的应用,包括控制系统电路以及如何通过已知条件选择如电流采样电阻,再通过调整参数确定电压-电流转换比例系统。通过试验验证了应用MAX472的有效性和可行性。
The working principle and function of MAX472 were introduced. The application of MAX472 in soft starting control system for asynchronous motor was emphatically introduced. The parameters calculation was carried out. The efficiency and applicability of this method was demonstrated by test results.
