摘要： A universal power converter of the present application may include a link stage between an input stage and an output stage that operates at a higher frequency than the frequency of the input power source. As a result, a more compact capacitor may be used, thus reducing the size of the power converter. In some embodiments, the link stage may be a partially resonant link that permits zero current switching (ZCS). ZCS operation may reduce switching losses during operation. Universal power converters of the present application utilizing ZCS may be implemented using naturally commutated switches, such as silicon controlled rectifiers (SCRs), instead of transistor switches. Such power converters utilizing SCRs may be more reliable than power converters utilizing transistor switches. Additionally, control circuitry required to operate such power converters may be simplified. Accordingly, a more compact, efficient, and reliable universal power converter may be achieved.
摘要翻译：本申请的通用功率转换器可以包括以比输入电源的频率更高的频率工作的输入级和输出级之间的链路级。因此，可以使用更紧凑的电容器，从而减小功率转换器的尺寸。在一些实施例中，链路级可以是允许零电流切换（ZCS）的部分谐振链路。 ZCS操作可能会降低运行中的开关损耗。使用ZCS的本申请的通用电力转换器可以使用诸如硅控整流器（SCR）之类的自然换向开关来代替晶体管开关来实现。利用SCR的这种功率转换器可能比使用晶体管开关的功率转换器更可靠。此外，可以简化操作这种功率转换器所需的控制电路。因此，可以实现更紧凑，高效和可靠的通用功率转换器。
