Description

隔离式交直流转换装置及其转换方法
技术领域
本发明与电源转换有关，特别是指一种隔离式交直流转换装置及其转换方法。
背景技术
按，隔离式电能传输***与一般接触型电能传输***最大的不同，在于隔离式电能传输***不须经由电力线直接传输能量，而是利用一隔离式变压器电磁耦合而将能量由一次侧传递至二次侧电路，然而隔离式变压器因其先天耦合不良因素，使得电力转换效率较低。因此，传统隔离式电能传输***常利用共振式阻抗匹配方式来提升电源转换效率，但是利用阻抗匹配电路方式实现的电路，甚易受隔离式变压器耦合系数参数影响，而达不到预期效果，造成电源转换效率低落。
此外，使用隔离式电能传输***的习用交直流转换装置在作动时，交流电源的输入电压与输入电流常会处于相位不同的情况，导致功率因子低且电流总谐波失真严重。此外，只有在内部整流电路输出的直流电源的电压高于该输出电容的电压时才会对输出端的电容进行充能，因此造成该电容充能时间短缩，导致导通电流的峰值随的增大，除造成输入电流波形失真及功率因子降低外，还会使得最后输出予负载的直流电能严重失真。
发明内容
本发明的目的在于提供一种隔离式交直流转换装置及其转换方法，除了具有高功率因子的优点外，可以同时兼顾快速响应与低涟波输出电压的目的。
为实现上述目的，本发明所提供的隔离式交直流转换装置，用以将一交流电源的电能转换后供予一负载，且包含一整流电路、一主动式功因校正电路、一隔离式变压器以及一自动电荷抽放(auto charge pump)电路。其中，该整流电路输入侧与该交流电源连接，用以接收该交流电源的电能后，转换成直流的电能并自其输出侧输出；另外，该输出侧具有一正电端以及一负电端。该主动式功因校正电路与该整流电路的输出端连接，用以接收该整流电路输出的电能并提升功率因子后输出，且包含有一第一二极管，其负极与该正电端连接；一第一电容，其一端与该第一二极管的正极连接；一电子开关，其一端与该第一电容另一端连接，而该电子开关另一端则与该负电端连接；一第一电感，其一端与该第一二极管的负极以及该正电端的连接处连接，而该第一电感另一端与该第一电容以及该电子开关的连接处连接；一第二二极管，其正极与该电子开关以及该负电端的连接处连接。该隔离式变压器具有一一次侧以及一二次侧，且该一次侧以及该二次测分别具有一第一端以及一第二端；该一次侧的第一端连接至该第一二极管与该第一电容的连接处，而该一次侧的第二端连接至该第二二极管的负极。该自动电荷抽放电路一侧电性连接该隔离式变压器，另一侧电性连接该负载；该自动电荷抽放电路包含有一第三二极管，其正极连接至该隔离式变压器二次侧的第二端，而负极则与该隔离式变压器二次侧的第一端电性连接；一第二电容，其一端连接该第三二极管的负极；一第二电感，其一端连接该第一电容的另一端，而另外一端则电性连接至该第三二极管的负极与该第二电容的连接处；一第三电容，与该负载并联，且其一端与该第二电容与该第二电感的连接处连接，而另一端则与该第三二极管的正极及该隔离式变压器二次侧的第二端的连接处连接。
依据上述构思，本发明的隔离式交直流转换装置的电源转换方法，包含有下列步骤：
A、导通该电子开关，使该整流电路输出的直流电对该第一电感器充能，且该第一电容的储能对该隔离变压器的一次侧充能，而该第二电容与该第二电感的储能对该第三电容充能，使该第三电容对该负载释能；
B、断开该电子开关以阻断该整流电路输出的直流电，使该第一电感的储能对该第一电容充能，并使该隔离式变压器的储能由二次侧对该第二电感、该第二电容与该第三电容充能，使该第三电容持续通过该负载释能；
C、导通该第三二极管，使该第二电容与该第二电感对该第三电容充能，使该第三电容持续该负载释能。
由此，通过上述的设计，便可以在电源转换时提高功率因子，更同时兼顾有快速响应与低涟波输出电压外的优点。

该第二二极管D2正极与该电子开关SW以及该负电端14的连接处连接。
该隔离式变压器30具有一一次侧31以及一二次侧32。该一次侧31与二次侧32分别具有一第一端311、321以及一第二端312、322。该第一端311连接至该第一二极管D1与该第一电容C1的连接处，而该第二端312则连接至该第二二极管D2的负极。
该自动电荷抽放电路40与隔离式变压器的二次侧32连接，且包含有三个二极管（第三二极管D3、第四二极管D4以及第五二极管D5）、二个电容（第二电容C2以及第三电容C3）以及一个电感（第二电感L2）。该些组件的连接关系如下所述：

该第三二极管D3的正极连接至该第二端322，而负极则与该第五二极管D2的负极连接以通过该第五二极管D5与该第一端321电性连接。
该第二电容C2一端则与该第三二极管D3的负极及该第五二极管D5的负极的连接处连接。
该第四二极管D4的正极与该第三二极管D3的负极、该第五二极管D5的负极及该第二电容C2的连接处连接。
该第二电感L2一端连接该第一电容C1的另一端，另外一端则与该第四二极管D4的负极连接，而通过该第四二极管D4电性连接至该第三二极管D3的负极、该第五二极管D5的负极及该第二电容C2的连接处。
该第三电容C3与该负载200并联，且一端与该第二电容C2与该第二电感L2的连接处连接，而另一端与该第三二极管D3的正极以及该第二端322的连接处连接。
于本实施例中，该些电容C1～C2、该些电感L1～l2、输入电压、输出电压、该电子开关SW的切换频率、以及该负载200的规格如表1所示。
由此，通过上述结构设计与规格，在利用下述的电源转换方法，便可达到增进电源转换效率的目的，而该方法包含有下列步骤：
A、请参阅图2，导通该电子开关SW，使该整流电路10输出的直流电对该第一电感器L1充能，且该第一电容C1的储能对该隔离变压器30的一次侧31充能，而该第二电容C2与该第二电感L2的储能对该第三电容C2充能，使该第三电容C3对该负载200释能。
B、请参阅图3，断开该电子开关SW以阻断该整流电路10输出的直流电，使该第一电感L1的储能对该第一电容C1充能，并使该隔离式变压器30的储能由二次侧32对该第二电感L2、该第二电容C2充能，并通过该第二电容C2与该第二电感L2形成的共振电路，将其储能传导至该第三电容C3，使该第三电容C3持续通过该负载释能。
C、请参阅图4，该第一电感L1停止释能，使该第一二极管D1截止，且当该第二电感L2的跨压大于该第三电容C3的跨压时，该第三二极管D3导通，使该第二电容C2与该第二电感L2对该第三电容C3充能，使该第三电容C3持续该负载200释能。
另外，每执行一次步骤A至步骤C后，则表示完成一次周期的作动。因此，在该隔离式交直流转换装置持续作动的情况下，于步骤C后，便继续重复执行步骤A至步骤C，直至该隔离式交直流转换装置停止作动。
通过上述的该自动电荷抽放电路40的设计，于每次作动周期中，使该第三二极管D3导通前后的整体电路结构改变，而可达到快速响应与低涟波输出电压的目的，同时可通过该电子开关SW的切换达到提升功率因子的目的。
另外，该第四二极管D4以及该第五二极管D5的设计还可有效地分别防止电路产生回流影响该隔离式变压器30以及该自动电荷抽放电路40的作动，进而使得整体电路更加地稳定，以提升该隔离式交直流转换装置能源转换与抑制涟波的效果。当然，在实际实施上，即使不使用该第四二极管D4以及该第五二极管D5仍可达到增进电源转换效率以及抑制涟波的目的。
再者，以上所述仅为本发明较佳可行实施例而已，且在电气特性以及电路动作原理相同的情况下，前述各电路组件的设置位置以及数量、以及举凡应用本发明说明书及申请专利范围所为的等效电路变化，理应包含在本发明的权利要求范围内。
