50kHz IGBT串联谐振感应加热电源研制
摘要
目前以IGBT为开关器件的串联谐振感应加热电源在大功率和高频下的研究是一个热点和难点,为弥补采用模拟电路搭建而成的控制系统的不足,对感应加热电源数字化控制研究是必然趋势。本文以串联谐振型感应加热电源为研究对象,采用TI公司的TMS320F2812为控制芯片实现电源控制系统的数字化。
首先分析了串联谐振型感应加热电源的负载特性和调功方式,确定了采用相控整流调功控制方式,接着分析了串联谐振逆变器在感性和容性状态下的工作过程确定了系统安全可靠的运行状态。本文设计了电源主电路参数并在Matlab/Simulink仿真环境下搭建了整个系统,仿真分析了串联谐振型感应加热电源的半压启动模式及锁相环频率跟踪能力和功率调节控制。
针对感应加热电源的数字控制系统,在讨论了晶闸管相控触发和锁相环的工作原理及研究现状下详细地分析了本课题基于DSP晶闸管相控脉冲数字触发和数字锁相环(DPLL)的实现,得出它们各自的优越性,同时分析了感应加热电源的功率控制策略,得出了采用数字PI积分分离的控制方法。本文采用TI公司的TMS320F2812作为系统的控制芯片,搭建了控制系统的DSP外围硬件电路,分析了系统的运行过程并编写了整个控制系统的程序。最后对控制系统进行了试验,验证了理论分析的正确性和控制方案的可行性。
At present take IGBT as the switch component's series resonance induction heating power source in the high efficiency and the high frequency under research is a hot spot and the difficulty. To cover the control system's insufficiency which uses the analogous circuit, the research of induction heating power digital control is the inevitable trend. In this article take the series resonance induction heating power supply as the object of study, mainly realizes the power source control system's digitization using TMS320F2812 of TI Corporation.
The phase control rectifier as the power control mode and the system safety reliable running status had been determined in the article through the analysis. The overall system had been built under the simulation environment of Matlab/Simulink in this article. The series resonance induction heating under power half voltage start pattern and phase-locked loop frequency track capacity and the power control had been analyzed though the simulation.
In view of induction heating power's digital control system, the work principle and the research present situation of phase control trigger of thyristor and phase-locked loop had been discussed in this article. Thyristor digital pulse triggering and the digital phase-locked loop (DPLL) in detail based on the DSP had been analyzed, and obtains them respective superiority. The induction heating power supply control strategy had been analyzed, and the control method of the digital PI the integral separation had been used. In this article TI Corporation's TMS320F2812 to take system's control chip had been used, control system's DSP periphery hardware circuit had been built, and overall system's procedure had been compiled though analyzed the system's work process. Finally the experiment of the control system has been carried, and confirmed the theoretical analysis accuracy and the control strategy feasibility.
