It can be used to exchange DC with the external input power supply. Or a fault-tolerant power supply with AC power input and excellent modular assembly convenience. [Prior Art] According to the current power supply market, there is a Redundant Power Supply Module, which provides fault-tolerant operation of N + 1 power supply for fault-tolerant power supply devices, with multiple power supplies. The hot extraction of the supplier can achieve this function. When one of the fault-tolerant power supply devices fails, the power supply can be immediately connected by the standby power supply to prevent the computer system from operating due to the power supply. Various faults are generated in the supply, and the faulty power supply can also be hot-drawn without shutting down. However, such a fault-tolerant power supply unit can only be applied to a single type of external input power source: such as AC input or DC input, because the type of power input is fixed and cannot be used. Interchange, so in the production assembly, there are two sets of fault-tolerant power supply devices that are divided into AC or DC power input, which will increase the manufacturing and management costs, which is not ideal. In addition, when the power supply causes some of the electronic components to act, the temperature will be too high. If the usage time is increased, if the high temperature is effectively eliminated, the power supply will be affected. The operation of this is followed by the problem of _ important; although the existing single-electric hybrid H or fault-tolerant crane supply silk towels will have a mixed design to adjust the power supply or fault-tolerant The temperature of the secret silk is not obvious when the money is not used. In particular, in the long-term use, M381826 can not achieve the effect of lowering the temperature in addition to noise, and it is necessary to increase the capacity due to the use of a cooling fan. The volume of the power supply device and the power consumption of the additional fan power, especially in the smaller size of the power supply device body limitation (height * width * depth, that is, 150mm * 86mm * N mm, soil 1 〇 picture; where N is Unlimited depth), the existing fault-tolerant power supply unit can only accommodate 1+1 power supplies. If 3+1 (or more) power supply output is required, it is necessary to add another body to accommodate Coupled with the power supply, so can not effectively improve volumetric efficiency, while consolidated into a breakthrough, it is necessary to improve. Therefore, how to improve the lack of the conventional fault-tolerant power supply should be an important direction for the industry to solve and overcome. Therefore, the creator of this creator has developed a solution based on the shortcomings of the conventional fault-tolerant power supply device and its unpredictable structure, hoping to develop a more power input. Selecting interchangeable, modular convenience, effectively increasing volumetric efficiency, and a modular, fault-tolerant power supply device with better heat dissipation without the use of a cooling fan to serve the public and promote the industry Development, the idea of a long time, and the creation of this creation.
