【摘要】：隨著電力電子技術(shù)的蓬勃發(fā)展,各種各樣的電子設(shè)備被越來(lái)越廣泛的應(yīng)用。如何能提高電能的利用效率,減少電子產(chǎn)品對(duì)于電網(wǎng)的諧波污染和提高電子產(chǎn)品的可靠性也越來(lái)越被重視。功率因數(shù)校正(Power Factor Correction,PFC)技術(shù)正是解開(kāi)這些難題的鑰匙。功率因數(shù)校正電路,通過(guò)PWM控制輸入電流,保持輸入電流跟隨整流正弦輸入電壓并且同相,有效的降低輸入電流諧波污染,實(shí)現(xiàn)功率因數(shù)校正。本文設(shè)計(jì)了一款CCM平均電流模式的PFC集成電路。論文首先對(duì)功率因數(shù)校正的原理和功率因數(shù)校正的方法進(jìn)行了簡(jiǎn)要的介紹,并且對(duì)本文所采用的有源功率因數(shù)校正進(jìn)行了詳細(xì)的介紹,包括常見(jiàn)的控制方法,電流導(dǎo)通模式和電流模型的分析。隨后對(duì)基于Boost變換器結(jié)構(gòu)工作在CCM平均電流模式下的電路模型進(jìn)行了穩(wěn)態(tài)分析,對(duì)雙環(huán)控制中的電流環(huán)和電壓環(huán)分別進(jìn)行了理論設(shè)計(jì)和零極點(diǎn)的分析以及數(shù)學(xué)推導(dǎo)。本文所設(shè)計(jì)的功率因數(shù)校正電路基于0.25μm 15V BCD工藝,工作在CCM平均電流模式下,其典型應(yīng)用為Boost拓?fù)浣Y(jié)構(gòu)的AC-DC變換電路。論文采用Hspice軟件對(duì)此功率因數(shù)校正電路的子模塊電路和整體電路進(jìn)行了仿真驗(yàn)證。在300W典型應(yīng)用下,系統(tǒng)的功率因數(shù)能達(dá)到0.99以上,THD控制在12%以內(nèi)。仿真結(jié)果表明該功率因數(shù)校正電路的各項(xiàng)指標(biāo)滿足設(shè)計(jì)要求,能有效的實(shí)現(xiàn)功率因數(shù)校正。
[Abstract]:With the rapid development of power electronics technology, a variety of electronic devices are more and more widely used.More and more attention has been paid to how to improve the efficiency of electric energy utilization, reduce the harmonic pollution caused by electronic products and improve the reliability of electronic products.Power Factor Correction (PFC) technology is the key to solve these problems.The power factor correction circuit controls the input current through PWM, keeps the input current following the rectifier sinusoidal input voltage and in phase, effectively reduces the harmonic pollution of the input current and realizes the power factor correction.In this paper, a CCM average current mode PFC integrated circuit is designed.Firstly, the principle of power factor correction and the method of power factor correction are briefly introduced, and the active power factor correction used in this paper is introduced in detail, including common control methods.Analysis of current conduction mode and current model.Then the steady state analysis of the circuit model based on the CCM average current mode based on the structure of Boost converter is carried out. The current loop and voltage loop in the double loop control are designed theoretically and the zero pole is analyzed as well as the mathematical derivation.The power factor correction circuit designed in this paper is based on 0.25 渭 m 15V BCD technology and works in the CCM average current mode. It is typically applied to the AC-DC conversion circuit with Boost topology.In this paper, Hspice software is used to simulate the sub-module circuit and the whole circuit of the power factor correction circuit.Under the typical application of 300W, the power factor of the system can reach above 0.99 and THD can be controlled within 12%.The simulation results show that the power factor correction circuit meets the design requirements and can effectively realize the power factor correction.
