摘要： The present invention provides a UPS and a DC-DC converter, where the UPS includes: a rectifier, an inverter, and a DC-DC converter. An input end of the DC-DC converter is connected to a BUS+, a BUS-, and an N wire. In this way, an input voltage is relatively low, and a device with low voltage resistance may be selected as a device in the DC-DC converter. Moreover, a load in the DC-DC converter is connected to a second switch tube through a second inductor rather than be directly connected to the second switch tube. Therefore, a high-frequency switch wave on the second switch tube may not affect the load. In this case, 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 embodiments of the 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.
