摘要： The present invention provides a UPS and a DC-DC converter. An input end of the DC-DC converter is connected to a BUS+, a BUS−, and an N wire. Therefore, an input voltage is relatively low, and devices with low voltage resistance may be selected as devices in the DC-DC converter. Moreover, a load in the DC-DC converter is connected to a switch tube through a inductor rather than be directly connected to the switch tube. Therefore, a high-frequency switch wave on the second switch tube may not affect the load. Accordingly, performance of the load and an anti-electromagnetic interference capability of a whole circuit may be improved. In addition, the DC-DC converter provided in present invention does not have a structure as complicated as that of a dual BUCK topology in the prior art. Therefore, the DC-DC converter, with respect to the dual BUCK topology, has less devices and lower costs.
摘要翻译：本发明提供了一种UPS和一个DC-DC转换器。 DC-DC转换器的输入端连接到BUS +，BUS-和N线。因此，输入电压相对较低，可以选择具有低电压电阻的器件作为DC-DC转换器中的器件。此外，DC-DC转换器中的负载通过电感器连接到开关管，而不是直接连接到开关管。因此，第二开关管上的高频开关波可能不会影响负载。因此，可以提高整个电路的负载的性能和抗电磁干扰能力。此外，本发明中提供的DC-DC转换器不具有与现有技术中的双BUCK拓扑结构复杂的结构。因此，相对于双BUCK拓扑，DC-DC转换器具有较少的器件和较低的成本。

摘要： An AC-AC converter configured of a forward converter that converts alternating current to direct current and a reverse converter that converts direct current to alternating current, wherein a first semiconductor switch series circuit, a second semiconductor switch series circuit, and a capacitor series circuit are connected in parallel, a first inductor is connected between one end of an alternating current input and a series connection point of the first semiconductor switch series circuit, a bidirectional switch is connected between the one end of the alternating current input and a series connection point of the second semiconductor switch series circuit, a second inductor is connected between the series connection point of the second semiconductor switch series circuit and one end of an alternating current output, and a series connection point of the capacitor series circuit is connected to the other end of the alternating current input and the other end of the alternating current output. Because of this, it is possible to keep the inductor loss of the rectifier sufficiently small when input voltage is within a specified range. Also, in addition to this, it is possible to reduce switching loss more than in heretofore known circuits when carrying out a compensation action.
