Induction heating power supply is the development trend of highfrequency, highcapacity, intelligent and green. The current highfrequency induction heating power of about a few hundred kilohertz frequency technology is relatively mature.In this paper, the series halfbridge induction heating power supply for the study, first principles on the basis of introduction of induction heating, induction heating power supply elaborated characteristics, domestic development and should its development trend. Secondly, it introduces the advantages and disadvantages of fullbridge inverter circuit in series with a series of halfbridge inverter circuit, halfbridge resonant inverter series has a simple structure, easy to control, good economic returns, etc. Therefore, the inverse analysis of the halfbridge series variable working principle of the bridge. Again, on the basis of a series of halfbridge inverter circuit designed on the specific circuit parameters were calculated for each device, and a reasonable choice of ponents. Finally, in a halfbridge series resonant power supply voltage by changing the rectifier filter after testing the leg voltage waveform, and the waveform is a brief analysis, the induction heating power should avoid noload and other experimental results.Keywords: induction heating。 series resonant halfbridge inverter。 課題研究的背景 ....................................1167。 感應(yīng)加熱電源的特點(diǎn) ...............................4167。 感應(yīng)加熱的發(fā)展趨勢 ...............................6第二章 半橋串聯(lián)諧振逆變器的主電路 .....................................................8167。 半橋串聯(lián)諧振逆變電路 ...............................................................9167。 原始數(shù)據(jù) .........................................12167。 確定整流晶閘管的參數(shù) ............................13167。 確定 IGBT 管參數(shù) .................................14167。 額定電流 ..................................15167。 計算感應(yīng)加熱線圈的電感及主電路諧振電容 ..........17167。 實驗結(jié)果 ........................................18167。但是，這種發(fā)熱長時間以來只是作為一種損耗而被人們關(guān)注。感應(yīng)加熱主要用于金屬熔煉、焊接、燒結(jié)、鋼管焊縫、熱裝配、金屬熱處理等領(lǐng)域。它不僅可對金屬材料直接加熱，而且也可對非金屬材料進(jìn)行間接式加熱，如單晶硅的加熱拉伸、半導(dǎo)體的提純、有機(jī)涂層的固化、人造寶石的熔煉等。如今，感應(yīng)加熱也開始滲透到了人們的日常生活中，如電磁爐等以感應(yīng)加熱原理制造的電器，為人們的日常生活提供了極大地方便。它可以將直流電轉(zhuǎn)變?yōu)楦哳l率的交流電，進(jìn)而產(chǎn)生交變磁場，處于交變磁場的導(dǎo)體感應(yīng)出渦流，從而使導(dǎo)體加熱。感應(yīng)加熱電源主要由整流器、逆變器、負(fù)載及控制和保護(hù)電路組成，其電路結(jié)構(gòu)如圖1．1所示。河南科技大學(xué)畢業(yè)設(shè)計論文2 感應(yīng)加熱電源基本結(jié)構(gòu)框圖 [11 感應(yīng)加熱的基本原理根據(jù)電磁感應(yīng)定律，處于交變磁場中的導(dǎo)體兩端會
