【摘要】：為了應(yīng)對(duì)全球氣候變暖和能源危機(jī)問題，世界各國都非常重視節(jié)能環(huán)保產(chǎn)品的開發(fā)。照明是消耗電力資源的主要方式，使用節(jié)能環(huán)保的LED燈具，替代傳統(tǒng)照明，是大勢(shì)所趨。LED驅(qū)動(dòng)電源的質(zhì)量對(duì)LED燈具至關(guān)重要。為響應(yīng)國家綠色照明政策，推動(dòng)LED照明的市場(chǎng)普及，對(duì)LED驅(qū)動(dòng)電源特點(diǎn)和關(guān)鍵技術(shù)的研究，具有一定的現(xiàn)實(shí)意義。 開關(guān)電源體積小、重量輕，被廣泛應(yīng)用于LED驅(qū)動(dòng)電源。本文針對(duì)大功率LED照明的特點(diǎn)，研究了開關(guān)電源比較熱門的兩項(xiàng)技術(shù)：有源功率因數(shù)校正技術(shù)和軟開關(guān)技術(shù)，通過對(duì)比分析，找到了適合LED驅(qū)動(dòng)電源的兩級(jí)功率因數(shù)校正設(shè)計(jì)方案。 對(duì)比了常用功率因數(shù)校正方案和控制方法的特點(diǎn)，選擇BCM峰值電流控制有源功率因數(shù)校正電路作為前級(jí)電路。研究了BCM峰值電流控制有源功率因數(shù)校正電路電感的設(shè)計(jì)方法，結(jié)合TDA4863芯片設(shè)計(jì)了控制電路和反饋網(wǎng)絡(luò)。分析常用隔離式拓?fù)浣Y(jié)構(gòu)特點(diǎn)，選擇反激式變換器設(shè)計(jì)后級(jí)電路，研究了反激電路準(zhǔn)諧振的實(shí)現(xiàn)過程和工作原理，選擇OB2203芯片設(shè)計(jì)了后級(jí)準(zhǔn)諧振反激電路。對(duì)恒流恒壓和EMI濾波電路進(jìn)行了研究和設(shè)計(jì)。 最后制作了一款高功率因數(shù)、高效率100瓦LED驅(qū)動(dòng)電源，并實(shí)現(xiàn)了有源功率因數(shù)校正級(jí)電路的變電壓輸出和整機(jī)輸出電流的可調(diào)，，提高了低輸入電壓時(shí)驅(qū)動(dòng)電源的整體效率和燈具的匹配能力。對(duì)相關(guān)波形、功率因數(shù)和效率進(jìn)行了測(cè)試，測(cè)試結(jié)果比較理想，達(dá)到了預(yù)期的指標(biāo)。
[Abstract]:In order to deal with the global climate change and energy crisis, countries all over the world attach great importance to the development of energy conservation and environmental protection products. Lighting is the main way to consume power resources. It is very important to use energy saving and environmental protection LED lamps instead of traditional lighting. The quality of LED driving power supply is very important to LED lamps. In order to respond to the national green lighting policy and promote the popularity of LED lighting market, it is of practical significance to study the characteristics and key technologies of LED driving power supply. Switching power supply is widely used in LED drive power because of its small size and light weight. According to the characteristics of high power LED lighting, two popular switching power supply technologies, active power factor correction (APFC) and soft switching, are studied in this paper. A two-stage power factor correction design scheme suitable for LED driving power supply is found. The characteristics of common power factor correction schemes and control methods are compared. The BCM peak current control active power factor correction circuit is selected as the leading circuit. The design method of active power factor correction (PFC) circuit inductance for BCM peak-current control is studied. The control circuit and feedback network are designed with TDA4863 chip. This paper analyzes the characteristics of isolation topology in common use, chooses the flyback converter to design the backstage circuit, studies the realization process and working principle of the flyback circuit quasi resonance, and chooses OB2203 chip to design the backstage quasi resonant flyback circuit. The constant current constant voltage and EMI filter circuit are studied and designed. Finally, a high power factor, high efficiency 100 watt LED drive power supply is made, and the variable voltage output of the active power factor correction stage circuit and the adjustable output current of the whole machine are realized. The overall efficiency of driving power supply and matching ability of lamps and lanterns are improved under low input voltage. The correlation waveform, power factor and efficiency are tested. The test results are satisfactory and reach the expected target.
