摘要

本文介绍了一种金属感应熔化电子技术系统的研究，该系统由一个晶体管桥并联电流逆变器组成，由一个不受控制的整流器和一个降压DC-DC转换器供电。为了稳定工作模式，使用了两个稳压器——逆变器用频率控制，在改变逆变器的控制频率时，通过改变DC-DC变换器的占空比来维持输入电流的滞回。该模型基于切换函数的使用，并对实际工艺过程中负荷的变化进行了模拟研究。从最优控制的综合和控制器系数的调整的角度来看，本文的结果也很有用。

Modelling of an Electronic Technological System for Induction Melting of Metals

The manuscript presents a study of an electronic technological system for induction melting of metals consisting of a transistor bridge parallel current inverter, powered by an uncontrolled rectifier and a step-down DC-DC converter. To stabilize the operating mode, two regulators are used - the inverter with frequency control and maintenance of the input current by changing the duty cycle of the DC-DC converter of hysteresis when changing the control frequency of the inverter. The model is based on the use of a switching function, and studies have been conducted simulating the changes in the load during a real technological process. The presented results are also useful from the point of view of the synthesis of optimal control and adjustment of the controller coefficients.
