Description
本發明是有關於一種交錯式高升壓比轉換器,且特別是有關於一種交錯式高升壓比軟開關式轉換器。 This invention relates to an interleaved high step-up ratio converter and, more particularly, to an interleaved high step-up ratio soft-switching converter.
近年來由於全球性能源危機以及環保意識提升,因此找尋替代能源即成為一個重要的課題。許多替代能源如太陽能、風能、水力、生質能與燃料電池等皆是相當有潛力的綠色能源。其中燃料電池是一種乾淨無污染的能源,如常被採用的質子交換膜燃料電池,但因其有活化損失、歐姆極化以及濃度損失的影響,導致輸出電壓隨負載增加而使得輸出電壓下降,即燃料電池隨著加載時輸出功率增加,使得輸出電壓逐漸下降,同時輸出電流卻逐漸上升,是屬於低電壓、高電流輸出之裝置。其他綠色能源也都具有輸出電壓較低的特性,使得後端應用範圍受限。 In recent years, due to the global energy crisis and environmental awareness, finding alternative energy has become an important issue. Many alternative energy sources such as solar energy, wind energy, hydropower, biomass and fuel cells are quite potential green energy sources. Among them, the fuel cell is a clean and pollution-free energy source, such as the proton exchange membrane fuel cell, which is often used, but due to its activation loss, ohmic polarization and concentration loss, the output voltage decreases with the load, which causes the output voltage to drop. As the output power of the fuel cell increases with loading, the output voltage gradually decreases, and the output current gradually rises, which is a device of low voltage and high current output. Other green energy sources also have lower output voltage characteristics, which limits the range of back-end applications.
因此發展出目前習知的交錯式高升壓比轉換器,可以將能源所輸出之低電壓升壓至高電壓再送至直流鏈(DC Link),以適用更廣後端應用範圍。然而目前交錯式高升壓比轉換器大多採取硬式切換,導致開關以及二極體切換損失大,電路效率低,且使得其損失功率累積在開關及二極體而容易發熱。 Therefore, the conventional interleaved high step-up ratio converter has been developed to boost the low voltage output from the energy source to a high voltage and then to the DC link for a wider range of back end applications. However, most of the interleaved high-boost ratio converters are hard-switched, resulting in large switching and diode switching losses, low circuit efficiency, and loss of power accumulated in the switches and diodes, which is prone to heat.
少數嘗試採用軟開關式的交錯式高升壓比轉換器,雖可改善切換損失問題,但為達成軟開關特性而需使用複雜 電路,使得成本高昂,實現不易。 A few attempts to use a soft-switching interleaved high step-up ratio converter can improve the switching loss problem, but it is complicated to achieve soft switching characteristics.

1.假設各開關元件包含第一主開關112、第一輔開關213、第二主開關122及第二輔開關223,與各二極體元件包含第一主二極體130、第二主二極體140、第一輔二極體214、第二輔二極體224、第一主背接二極體113、第二主背接二極體123、第一輔背接二極體215、第二輔背接二體225皆視為理想元件,即無導通壓降,且導通電阻及截止電流皆可忽略不計。 1. It is assumed that each switching element includes a first main switch 112, a first auxiliary switch 213, a second main switch 122, and a second auxiliary switch 223, and each of the diode elements includes a first main diode 130 and a second main unit The pole body 140, the first auxiliary diode 214, the second auxiliary diode 224, the first main backing diode 113, the second main backing diode 123, the first auxiliary backing diode 215, The second auxiliary backing body 225 is regarded as an ideal component, that is, there is no conduction voltage drop, and the on-resistance and the off current are negligible.
2.第一共振電容211為第一主開關112之寄生電容及其外加之電容的總值;第二共振電容221為第二主開關122之寄生電容及其外加之電容的總值。 2. The first resonant capacitor 211 is the total value of the parasitic capacitance of the first main switch 112 and its applied capacitance; the second resonant capacitor 221 is the total value of the parasitic capacitance of the second main switch 122 and its applied capacitance.
3.假設開關切換時間及共振時間,相對於第一儲能電感111電流i L1 、第二儲能121電感電流i L2 、箝位電容150電壓v C1 及輸出電容161電壓v o 的變化而言是極其短暫的,所以在切換週期T內,可將第一儲能電感111電流i L1 、第二儲能電感121電流i L2 、箝位電容150電壓v C1 及輸出電容161電壓v o ,分別視為常數值,即i L1 =I L1 ,i L2 =I L2 ,v C1 =V C1 ,v o =V o 。 3. Assume that the switching time and the resonance time are relative to the change of the first energy storage inductor 111 current i L1 , the second energy storage 121 inductor current i L2 , the clamp capacitor 150 voltage v C1 , and the output capacitor 161 voltage v o . It is extremely short, so in the switching period T , the first energy storage inductor 111 current i L1 , the second energy storage inductor 121 current i L2 , the clamp capacitor 150 voltage v C1 and the output capacitor 161 voltage v o , respectively Treated as a constant value, ie i L1 = I L1 , i L2 = I L2 , v C1 = V C1 , v o = V o .
以下依據各開關切換及各二極體導通及截止狀態,將本實施方式操作於一週期T之狀態分為14個操作模式,分別為模式1至模式14,以說明各主要元件之訊號波形: 在模式1之前,即當時間t為時間點t 0 之前,此時第一主開關112與第一輔開關213皆為截止,而第二主開關122與第一主二極體130為導通狀態,可知跨於第一主開關112之電壓v ds1 及跨於第一共振電容211之電壓為V o /2。 In the following, according to the switching of each switch and the on and off states of the diodes, the state in which the present embodiment operates in one cycle T is divided into 14 operating modes, which are mode 1 to mode 14, respectively, to illustrate the signal waveforms of the main components: Before the mode 1, that is, before the time t is the time point t 0 , the first main switch 112 and the first auxiliary switch 213 are both turned off, and the second main switch 122 and the first main diode 130 are turned on. It can be seen that the voltage v ds1 across the first main switch 112 and the voltage across the first resonant capacitor 211 are V o /2.
模式1為當時間t介於時間點t 0 至時間點t 1 之間,此時第一主二極體130仍為導通狀態,而第一主開關112延遲導通,由第一輔開關213先行導通,第一共振電感212上電壓之為V o /2,第一共振電感212之電流i Lr1由初始值零呈直線上升,可得:
模式2為當時間t介於時間點t 1 至時間點t 2 之間,此期間第一共振電感212之電流i Lr1上升至I L1,第一共振電容211之電壓v Cr1為v Cr1(t)=V o /2,第一主二極體130開始進入截止,第一輔開關213持續導通,第一共振電感212與第一共振電容211形成共振回路,此時第一共振電感212之電流i Lr1持續上升,第一共振電容211之電壓v Cr1下降,可得:
模式3為當時間t介於時間點t 2 至時間點t 3 之間,在模式3中,第一共振電容211之電壓v Cr1承接模式2持續下降至零,甚至為微小負電壓,使得第一主背接二極體113順向導通,此時第一主開關112之電壓v ds1為零;於時間t
等於時間點t 3 時模式3終止,同時可開始觸發第一主開關112以達成零電壓切換,且此時可將第一輔開關213由導通狀態切換至截止狀態。可得此時第一共振電感212電流i Lr1 及第一主開關112電流i s1為:
模式4為當時間t介於時間點t 3 至時間點t 4 之間,進入模式4時第一主開關112導通,第一輔開關213截止;第二主開關122導通,第二輔開關223截止,此時儲存至第一共振電感212之能量,藉由第一輔二極體214導通將能量釋放至負載。在第一輔二極體214導通時,第一輔開關213兩側電壓為V o ,第一共振電感212之端電壓為-V o ,因此可得第一共振電感212之電流i Lr1:
模式5為當時間t介於時間點t 4 至時間點t 5 之間,此期間第一主開關112導通,第一輔開關213截止;第二主開關122導通,第二輔開關223截止,此時第一主開關112電流i S1 、第二主開關122電流i S2 、第一共振電容211電壓v Cr1 及第二共振電容221電壓v Cr2 分別為:i S1=I L1,i S2=I L2,v Cr1(t)=0,v Cr2(t)=0,t 4 t t 5;當第二主開關122截止時,時間t為時間點t 5 ,此時模式5結束。 Mode 5 is when the time t is between the time point t 4 and the time point t 5 , during which the first main switch 112 is turned on, the first auxiliary switch 213 is turned off, the second main switch 122 is turned on, and the second auxiliary switch 223 is turned off. At this time, the first main switch 112 current i S1 , the second main switch 122 current i S2 , the first resonant capacitor 211 voltage v Cr1 and the second resonant capacitor 221 voltage v Cr2 are respectively: i S 1 = I L 1 , i S 2 = I L 2 , v Cr 1 ( t )=0, v Cr 2 ( t )=0, t 4 t t 5 ; When the second main switch 122 is turned off, the time t is the time point t 5 , at which time the mode 5 ends.

呈直線上升,第二主二極體140電壓v D2由V o /2呈直線下降,可得第二共振電容221之電壓v Cr2 為:
模式8為當時間t介於時間點t 7 至時間點t 8 之間。進入模式8時,第一主開關112導通,第一輔開關213截止;第二主開關122進入截止,第二輔開關223導通,跨於第
二主開關122、第二共振電容221及箝位電容150之電壓均為Vo/2。於模式8期間,第二主二極體140仍然為導通狀態,第二主開關122延遲導通,由第二輔開關223先行導通,第二共振電感222上之電壓為Vo/2,第二共振電感222之電流i Lr2由零呈直線上升,於是可得第二共振電感222電流為:
模式9為當時間t介於時間點t 8 至時間點t 9 之間。於模式9期間,第二共振電感222之電流i Lr2繼續上升,第二共振電容221之電壓v Cr2為v Cr2(t)=V o /2,第二主二極體140截止,第二輔開關223持續導通,第二共振電感222與第二共振電容221形成共振回路,此時第二共振電感222之
電流i Lr2持續上升,第二共振電容221之電壓v Cr2下降。因共振阻抗Z o2 為,共振頻率ω o2 為;則可得第二共振電感222之電流i Lr2及第二共振電容221之電壓v Cr2分別為:
模式10為當時間t介於時間點t 9 至時間點t 10 之間。於模式10期間,承接模式9第二共振電容221之電壓V Cr2持續下降至微小負電壓,使得第二主背接二極體123順向導通,此時第二主開關122之電壓V ds2為零。於時間t為時間點t 10 時,模式10終止,同時開始觸發第二主開關122使其達成零電壓切換,同時第二輔開關223由導通狀態切換至截止狀態。可得第二共振電感222之電流i Lr2 及第二主開關122之電流i S2 為:
模式11為當時間t介於時間點t 10 至時間點t 11 之間。進入模式11時,第一主開關112導通,第一輔開關213截止;第二主開關122導通,第二輔開關223截止,此時儲存至第二共振電感222之能量,藉由第二輔二極體224導通將能量釋放至負載。在第二輔二極體224導通時,第二輔開關223兩端電壓為Vo,第二共振電感222之端電壓為-Vo。可得第二共振電感222電流i Lr2 為:
模式12為當時間t介於時間點t 11 至時間點t 12 之間。於模式12時,第一主開關112導通,第一輔開關213截止;第二主開關122導通,第二輔開關223截止,此時可得第一主開關112電流i S1 、第二主開關122電流i S2 、第一共振電容211電壓v Cr1 及第二共振電容221電壓v Cr2 為:i S1=I L1,i S2=I L2,v Cr1(t)=0,v Cr2(t)=0,t 11 t t 12;當第一主開關112截止時,時間t為時間點t 12 ,模式12終止。 Mode 12 is when time t is between time point t 11 and time point t 12 . In mode 12, the first main switch 112 is turned on, the first auxiliary switch 213 is turned off; the second main switch 122 is turned on, and the second auxiliary switch 223 is turned off. At this time, the first main switch 112 current i S1 and the second main switch are obtained. 122 current i S2 , first resonant capacitor 211 voltage v Cr1 and second resonant capacitor 221 voltage v Cr2 are: i S 1 = I L 1 , i S 2 = I L 2 , v Cr 1 ( t )=0, v Cr 2 ( t )=0, t 11 t t 12 ; When the first main switch 112 is turned off, the time t is the time point t 12 and the mode 12 is terminated.
模式13為當時間t介於時間點t 12 至時間點t 13 之間。進入模式13時第一主開關112截止,第一輔開關213截止;第二主開關122持續導通,第二輔開關223截止,此時對第一共振電容211充電,第一共振電容211之電壓v C r1呈直線上升,第一主二極體130電壓v D1 由Vo/2呈直線下降,可得第一共振電容211之電壓v Cr1 為:
模式14為當時間t介於時間點t 13 至時間點t 14 之間。其中當時間t為時間點t 14 時,電路組態又回復為相同於時間t為時間點t 0 時之電路組態,意即從模式1至模式14即完成一週期之操作。於模式14期間,第一主開關112截止,第一輔開關213截止;第二主開關122導通,第二輔開關223截止。又此期間第一主二極體130導通,將第一儲能電感111之能量釋放給箝位電容150,對箝位電容150進行充電,此時第一共振電容211之電壓為Vo/2,第一主二極體130之電流i D1為i D1(t)=I L1。當時間t為時間點t 14 時,可得第一主開關112電流i S1 、第二主開關122電流i S2 、第一共振電容211電壓v Cr1 、第二共振電容221電壓v Cr2 為:
