本文所介绍的节能控制器采用了单片微机技术,由三端双向可控硅构成三相调压电路,过零触发方式.控制器以电动机的电流作为采样值,并根据采样值的大小自动调节输入功率.这是应用于电动机节能装置中最新的一种节能控制器.文中对控制器的节电原理、系统硬件构成做了较详细的论述,并给出了主要软件的流程图.
Energy-saving controller introduced in this paper uses a single-chip microcomputer technology, composed of three-phase triac voltage regulator circuit, zero-crossing trigger mode. The controller to the motor current as a sample value, and automatically according to the size of the sample value Adjust the input power.This is the latest energy-saving controller used in the motor energy-saving device.This paper makes a detailed discussion of the controller’s power-saving principle, the system hardware structure, and gives the flow chart of the main software.
