Abstract: A DC converter includes a non-isolated conversion module and an isolated conversion module. The non-isolated conversion module is implemented based on a redundant structure and has a first power conversion loop, a second power conversion loop, and an energy storage element. The first and second power conversion loops are connected and share the energy storage element. The energy storage element is further connected to an input terminal of the isolated conversion module. The first and second conversion loops of the non-isolated conversion module convert DC power outputted from two battery sets and output the converted power to the isolated conversion module. The isolated conversion module further supplies DC power to a load. Accordingly, power supply systems using the foregoing DC converter can reduce the number of transformer therein and thus size reduction of the power supply system can be achieved.

Abstract: An AC backup power system controls a power supply to selectively connect to a primary AC power source or a backup AC power source through a switching module. The switching module is controlled by a monitoring module. The monitoring module has a power monitoring unit, a first circuit switch, a second circuit switch, and a first processor. When the power monitoring unit detects an interruption of primary AC current, the first circuit switch that is normally closed is immediately turned off. The first processor then drives the switching module to connect to the backup AC power source. Once the backup AC power source reaches the zero-crossing point, the second circuit switch is turned on so that the backup AC power source provides power to the power supply. The power supply receives power at the zero-crossing point to avoid problems of sparks and coke deposition.
