低成本高可靠供电方案（国外英文资料） Based on the current technology status of the UPS for the IT system design a small investment, high efficiency, redundant power supply mode which accords with the situation of China - string for each type of dual power supply system, which to develop a static bypass switch, the function of each component in the UPS system can get into full play. In recent years, information technology, with unprecedented speed changing peoples study, work and life, make information system become an indispensable economic activities support platform. In order to ensure the reliable operation of various information systems, the protection of its power supply system is on the agenda. For important IT systems, IT is the basic consensus that UPS provides secure, stable, reliable 365 times 24 hours of power supply. Traditional IT systems UPS power solutions Solution 1: the UPS machine power. This is the simplest of UPS power solutions. How it works: When normal, the load is supplied by the UPS and the reverse double conversion. When the rectifier fails or the input power goes away, the reverse of the backup battery pack is converted to the load. When the inverter fails or the backup battery has no electricity, the static by-pass is powered by the market. Disadvantages: no redundancy backup, no guarantee for the safety of the equipment. Scenario 2: UPS twin sets power supply. The UPS system is made up of a host and a standby unit, and the standby machine is connected to the main channel. How it works: When the main engine is working properly, the load is supplied by the UPS and the reverse double transform. When the engine rectifier fails or the input power is lost, the load is powered by the reverse of the back-up battery. When the inverter fails or the backup battery has no electricity, the static by-pass is powered by the standby. When the UPS host needs to be maintained, the entire system can still be loaded by a by-pass standby system. Disadvantages: when the backup
