Description

具有降压功率变换器特性的全波升降压功率变换器
本发明涉及开关式功率变换器。特别是，本发明涉及其中有利地集成了基本降压或升压变换器形式的特征和特性的开关式功率变换器。更具体地说，本发明涉及基本降压变换器形式与以前集成的升降压变换器形式的有利集成。
在开关式电源中通常使用三种基本的电路系列，即降压、升压和升降压(通常称作“回扫”)。升降压(回扫)变换器很可能是有利地集成基本降压和升压变换器形式的最早例子。虽然有些管理当局把升降压变换器看作是一种基本形式，但是另一种主要意见认为升降压变换器是一种集成形式。
无论升降压变换器形式的成因怎样，管理当局关于升降压变换器形式，M＝D/(1-D)，和升压变换器形式，M＝1/(1-D)两者的连续式输出控制传递函数的布局特性有一致意见。这种一致意见认为，在所有连续式脉冲宽度调制控制的固定频率的开关式升压和升降压变换器形式中，都存在非最小相特性，即右半s平面零点。这种叫做RHP零点的一阶特性归因于(1-D)项所相应而生的感应电流/负载电流的不连续性。这种RHP零点在降压系列的电路中从不出现。作为一种“非常讨厌的右半平面零点”的痛骂方式，以及一种“不可能补偿”的绝望情绪，这种RHP零点已被歪曲地戏称为“在每个获得升压的变换器的传递函数中无需额外费用就包括了右半平面零点”。已认定不存在与全波降压(正向)变换器形式等效的升降压(回扫)变换器形式。各种各样减轻这种RHP零点的努力包括不连续方式操作、前沿调制、功率和控制元件值控制，以及平均电流方式控制技术。现代变换器控制回路补偿技术广泛地提出有效地抑制这种RHP零点效应的要求。
于1967年作出假设，并在1972年得到分析证明，这种RHP零点效应二十余年来一直是连续认真研究的课题。这种努力的理由在升降压变换器形式的种种有利特性的集合中得到了体现，在这些有利特性集合中，有简单性、容易实现多输出、复合电压传递函数、宽输入线范围、降低的半导体应力、负载保护，以及和正向(降压)变换器相同的功率密度和效率。
尽管没有经受住这种RHP零点效应，但是专门以单端和全波两种布置工作，以及经广大泛围公共领域的努力，升降压变换器形式(回扫)已经在功率转换应用中得到了广泛的使用。
上述讨论连同适当确定的应用准则使其相当清楚，即如果这种RHP零点效应被消除，那么已经十分普遍的升降压变换器形式将会得到更广泛的应用。
本发明是一种连续式、全波、升降压(回扫)、脉冲宽度调制控制、固定频率、开关式的功率变换器，其中单个通量交换中介(储能感应器)这样置于(耦合在)交变(变换)电源与负载开关装置之间，以便同时提供标准升降压变换器电压传递函数，M＝D/(1-D)，以及在交变D时段期间为连续电源，在同时(1-D)时段期间为不连续电源，和在交变D和同时(1-D)两个时段期间为连续负载的特有的全波降压感应电流特性。
由于RHP零点从不在降压系列的电路中出现，所以这种变换器布局不呈现在讨论现有技术时所述的特有的获得升压的RHP零点，然而保持所有其它的内在全波升降压特性。响应常规控制装置，回路带宽仅由理论上脉冲调制率最大值所限制。
整个功率磁函数，即感应和变换(隔离)两部分，可以用单个磁元件得到，全波正向变换器的回扫等效可以用单个变换器芯得到。
参考附图，将会进一步理解本发明及其优选实施例的详细情况，其中：

图9连同电压、电流和传递函数特征，示意说明本发明的隔离式单磁变换器实施例。
图9A连同电压和电流特征，说明图9的磁结构。
为了说明本发明，假定理想开关，单向导电装置，以及磁性元件。理想化的磁特性包括用于下文讨论的变换器T11和T12的常规低磁阻磁芯结构，以及用于L的常规磁阻相对较高的磁芯结构，这样实现是为了获得必要的安匝(磁势)特征。M项是理想电压转换率，用D项来表示。D项是开关闭合时间tON，表示为(T)的函数。(T)项是一个全波操作周期，以任意时间单位表示。
1。现在参考图3和图3A，其时间、电压和电流特征在图6中连同时间、电压和电流表达式，用(T)、(A)、(E)、(F)和(H)表示。给定n＝0.5，可见对图3现有技术获得降压的电路的电压传递函数应用交变(全波)开关装置将表示2D项，即M＝n2D/{1+2D(n-1)}＝0.5(2D)/{1+2D(-0.5)}＝D/(1-D)。这个表达式精确地模拟常规全波降压变换器，其中如施加在各开关上的D项被全波降压感应器的Et等效特征有效地加倍，也就是，在稳态操作下，在每个开关周期上感应器两端之间电压的平均值必须为零。[(Ein-Eout)2D]+[-Eout(1-2D)]＝0，2DEin-2DEout-Eout+2DEout＝0，2DEin-Eout＝0，Eout＝2DEin，M＝2D。
2.现在参考图7和图7A，其时间、电压和电流特征在图6中连同时间、电压和电流表达式，用(T)、(A)、(B)、(C)、(D)、(E)、(F)、(G)、(H)、(I)、(J)、(K)、(L)和(M)表示。
开关S11或S12的交替闭合tON将表示对应变换器T11或T12的Np、NT和Ns两端之间的Ein。对应的单向导电装置D11或D12将为不导通。组合的变换器和感应器的作用将通过导电的非对应单向导电装置D11或D12，表示非对应变换器T11或T12的Np、NT和Ns两端之间的Eout。配置并极化T11的Np与T12的NT的串联组合以及T11的NT与T12的Np的串联组合，以便在每个tON时段期间表示电压Ein-Eout，即电压(A)。这些串联组合并联连接在感应器L两端之间，这样通过导电的非对应单向导电装置D11或D12，把感应器L串联置于Ein与Eout之间。在每个tON时段期间，感应器L电流(G)与电源电流(E)、开关电流(I)或(J)、单向导电装置电流(L)或(M)，以及输出电流(H)相连续。
同时断开开关S11和S12将因感应器L中的常规安匝(磁势)守恒而允许电压(A)的极性反向。单向导电装置D11和D12都导通，表示T11的Ns和T12的Ns两端之间的电压Eout，这个电压Eout由T11和T12的变换率(Np+NT)/Ns，即2∶1，表示为L两端之间电压。电压(A)在每个(T/2-tON)时段期间为-2Eout。图7A的全波回扫感应器L的Et等效表示为[(Ein-Eout)2D]+[-2Eout(1-2D)]＝0，2DEin-2DEout-2Eout+4DEout＝0，2DEin-2Eout+2DEout＝0，DEin+DEout＝Eout，DEin＝Eout-DEout，EinD＝Eout(1-D)，Eout＝Ein[D/(1-D)]，M＝D/(1-D)，还是取交替地施加在开关装置上的D项。感应器L电流(G)通过比率Ns/(Np+NT)，即1∶2并联变换为输出电流(H)。各单向导电装置传导电流(K)，这些电流的和是电流(F)。感应器L电流(G)在每个(T/2-tON)时段期间与各单向导电装置电流(K)和输出电流(H)同时连续。感应器L电流(G)在开关装置S11或S12闭合时段tON期间为连续电源，在开关装置S11和S12同时断开时段(T/2-tON)期间为不连续电源，以及在tON和(T/2-tON)两个时段期间为连续输出。因此，IL＝IM，IR(LOAD)＝2DIM+(1-2D)2IM，IR(LOAD)＝2IM[D+(1-2D)]，IR(LOAD)＝2IM(1-D)，IM＝0.5IR(LOAD)/(1-D)。通过集成电容器C2，连续的感应器L电流(G)/输出电流(H)以IR(LOAD)传送，这样表示使用负载R(LOAD)两端之间的Eout。
3.现在参考图8和图8A，其时间、电压和电流特征在图6中连同时间、电压和电流表达式，用(T)、(A)、(B)、(C)、(D)、(E)、(F)、(G)、(H)、(I)、(J)、(K)、(L)和(M)表示。除感应器L两端之间所表示的电压(A)是通过把T11和T12集成在单个低磁阻磁芯结构中而获得外，这个电路功能上与图7和图7A的电路相同。感应器L保持为一个分开的磁阻相对较高的磁芯结构。表示任一个Np两端之间的Ein和表示任一个非对应Ns两端之间的Eout的通量总和在tON时段期间产生Nt电压Ein-Eout。在(T/2-tON)时段期间同时表示各Ns两端之间的Eout的通量总和产生Nt电压，-2Eout。磁积分和通量总和技术按功率转换规定适当地建立。
4.现在参考图9和图9A，其时间、电压和电流特征在图6中连同时间、电压和电流表达式，用(T)、(A)、(B)、(C)、(D)、(E)、(F)、(H)、(I)、(J)、(K)、(L)和(M)表示。除表示虚线圈NEMF两端之间的电压(A)还是安匝(磁势)特征的模拟量外，这个电路功能上与图7和图7A电路相同。NL和NT线圈集成在T11和T12中。磁结构的外臂保持相对低的磁阻特性。感应器L的磁阻相对较高的磁特性集成在磁结构中臂中。感应器电流(G)的平均值现在是IM，它是较高磁阻的磁电流，为电流(I)、(J)和(K)的合成。磁积分和通量总和技术与第3段那些技术的出处，以及两线圈架推导共享。
5.现在参考图4和图4A，其时间、电压和电流特征在图6中连同时间、电压和电流表达式，用(T)、(A)、(B)、(C)、(D)、(E)、(F)、(H)、(I)、(J)、(K)、(L)和(M)表示。除在这个非隔离式实施例中缺少Ns线圈外，这个电路功能上与图9和图9A电路相同。
6.现在参考图5和图5A，其时间、电压和电流特征在图6中连同时间、电压和电流表达式，用(T)、(A)、(B)、(C)、(D)、(E)、(F)、(H)、(I)、(J)、(K)、(L)和(M)表示。除在这个隔离式多输出实施例中外加Ny线圈外，这个电路功能上与图9和图9A电路相同。
7.现在参考图1，这个电路实施了本发明的标准形式，并且功能上与电压极性和电源/负载方向无关。单、双、三和四象限方式函数是显而易见的。
8.在阅读本公开文本基础上，本发明的上述和其它特点(如本发明技术方案中所述)对本领域技术人员将是显而易见的。同样将显而易见，对任何给定的操作方式，控制装置CM可以用各种各样的方式实现。同样还显而易见，布局可以加以调配和扩增，以布置所有现有技术全波和多相电路几何形状，即半桥形、全桥形等。
在阅读本公开文本基础上，本发明的其它应用、变化和分支对本领域技术人员将变得显而易见。如附加权利要求所限定那样，这些了解打算包括在本发明的范围之内。
