基于DSP的大功率超音频感应加热电源研究
|
摘要
随着制造业技术的发展,超音频感应加热电源因其具有诸多优点而在现代化生产中发挥着越来越大的作用。目前,国内超音频感应加热电源发展非常迅速,但是在电源的数字化、容量、电路结构等方面还有待改进。因此本文主要对超音频感应加热电源电路理论知识和以TMS320F2812型号DSP为主控芯片的数字化控制系统进行了研究。
本文首先研究了感应加热电源的主电路结构,详细分析了逆变器与谐振负载不同组合的电路特点并结合本项目的实际需要,确定选取电压型串联谐振电路。然后通过分析比较确定采用直流侧斩波的方式进行功率调节,接下来进一步确定了主电路中所用到的元器件的参数,为样机的制作提供依据。
感应加热电源的控制部分主要包括整流侧的斩波控制和逆变侧的频率跟踪控制。整流侧的斩波控制指通过调节斩波器的驱动脉冲占空比来达到功率调节的目的。在逆变侧控制系统中主要实现频率的自动跟踪、IGBT的驱动等功能。本文通过分析确定了基于TMS320F2812型号DSP为主控芯片的数字化控制系统,设计了相应的外围电路并进行了软件编程。
主电路的设计和控制的实现通过了仿真和试验。在MATLAB/SIMULINK和Pspice环境中分别对基于FUZZY-DPLL控制策略的感应加热电源和本文所采用的主电路进行建模分析,系统的仿真结果和试验都验证了本文理论研究与设计方案的可行性与正确性。

Firstly, the paper researches on the induction heating power main circuit, analyses the difference about the resonant load and different combinations, combines with the actual need, determined voltage series resonance circuit. By analyzing and comparing, BUCK converter scheme regulation is adopted as power modulation method, then the parameter of component is calculated to supply basis for making model machine.
Induction heating power’s control system contains of BUCK converter control in rectifier and frequency tracking control in inverter. The power’s control is used by DSP’S module to output pulse for BUCK converter, control of inverter mainly contains frequency tracking, driving and protecting of IGBT. The paper finally determined the digital control system of based on TMS320f2812 DSP, and designed the corresponding peripheral circuits and programmed software.
The design and control implement of main circuit are through the simulation and experiments. The modeling analysis in MATLAB and pspice environment is for based on the FUZZY-DPLL control policy's and the main circuit of induction heating power source, The simulation results and some tests have proved that the design in this paper is reasonable, and the analysis of the circuits are correct.
