【摘要】：本課題的研究對象是高頻感應(yīng)加熱電源。在對感應(yīng)加熱電源的發(fā)展過程以及國內(nèi)外感應(yīng)加熱電源的發(fā)展現(xiàn)狀了解的基礎(chǔ)上，分別對應(yīng)用于感應(yīng)加熱電源的兩種諧振方式進行了分析，并根據(jù)課題需要，選定了并聯(lián)諧振作為本課題中高頻感應(yīng)加熱電源的逆變拓撲結(jié)構(gòu)。然后對高頻感應(yīng)加熱電源電流工作模式，和電流饋電拓撲做了簡要介紹，根據(jù)電流模式的不足對電路做了斜率補償分析，并根據(jù)實際電路需要對控制電路反饋電流做了斜率補償。然后確定了控制芯片為電流型控制芯片。 本文對并聯(lián)諧振逆變電路的工作狀態(tài)進行了分析，容性、阻性和感性情況下分析。對主電路中的主要器件進行了計算和選取，并且對輔助電源、變壓器、電流互感器和濾波電感等元器件具體制作做了計算和制作過程做了詳細的介紹。整個設(shè)計的恒流源輸出功率為3kW，同時根據(jù)本文設(shè)計要求選擇了UC3846芯片，并根據(jù)UC3846的同步端，實現(xiàn)了同步控制及頻率跟蹤，對精密全波整流電路、保護電路和驅(qū)動電路進行了計算設(shè)計。設(shè)計了開機掃頻電路，并配合頻率跟蹤電路實現(xiàn)了電源的軟啟動。在樣機實驗時遇到了一些實際問題，對其分析并提出了解決的辦法，最后使電源實現(xiàn)了比較理想的工作狀態(tài)。 本文結(jié)尾給出了主電路及驅(qū)動電路的原理圖和PCB打樣圖。在實驗中，測得了部分實際波形。從結(jié)果看出每部分都能達到預(yù)期結(jié)果。最后完成整機調(diào)試，通過實驗波形驗證，本設(shè)計達到了預(yù)期的要求。
[Abstract]:The research object of this subject is high frequency induction heating power supply. Based on the understanding of the development process of induction heating power supply and the development status of induction heating power supply at home and abroad, two kinds of resonance modes applied to induction heating power supply are analyzed, and according to the need of the subject, The parallel resonance is selected as the inverter topology of the high frequency induction heating power supply. Then, the current working mode and current feed topology of high frequency induction heating power supply are briefly introduced, and the slope compensation analysis of the circuit is made according to the deficiency of current mode. The feedback current of the control circuit is compensated by slope according to the actual circuit requirement. Then the control chip is determined to be a current-mode control chip. In this paper, the working state of parallel resonant inverter circuit is analyzed, including capacitive, resistive and inductive conditions. The main components in the main circuit are calculated and selected, and the fabrication process of auxiliary power supply, transformer, current transformer and filter inductor is introduced in detail. The output power of the whole constant current source is 3kW, and the UC3846 chip is selected according to the design requirements of this paper. According to the synchronous terminal of UC3846, the synchronous control and frequency tracking are realized, and the precision full wave rectifier circuit is realized. Protection circuit and drive circuit are calculated and designed. The frequency sweep circuit is designed, and the soft start of the power supply is realized with the frequency tracking circuit. Some practical problems are encountered in the prototype experiment, and the solutions are put forward and analyzed. Finally, the ideal working state of the power supply is realized. At the end of this paper, the schematic diagram and PCB proofing diagram of main circuit and drive circuit are given. In the experiment, some actual waveforms are measured. From the results, we can see that each part can achieve the expected results. Finally, the debugging of the whole machine is completed, and the experimental waveform verifies that the design meets the expected requirements.
