Electric appliance SW5 and the second single-pole double-throw relay SW6, which is closed, throws cutter-contact point and normally opened contact (end 1-2), and inverter module 300 is inverse
Become output and be transferred to server power supply, the transition power supply of battery BAT power supply is switched to as alternating current；
Occur if 2.2, alternating current is directly switch to battery BAT power supply and has many problems, it may be battery BAT energy
The anti-utility grid that pours into generates danger, is switched to battery indirectly, can reduce the heavy current impact to battery, prevent lithium battery from protecting
Shield malfunction, prevents cell damage, or server is caused to power off risk；Therefore transition power supply is made by inverter module 300, passed through
Inverter is transferred to server power supply, powered as transience transition by above-mentioned control operation.After the completion of transition power supply, control
Molding block 100 controls inverter module 300 and closes, and controls the first field-effect tube MOS1, the second field-effect tube MOS2 conducting, closure
Battery BAT energy is directly fed server, battery BAT direct current supply at this time by third relay SW3 and the 4th relay SW4
Efficiency nearly reach 100%.Wherein, since the conducting speed of relay is slow, there are the risks of power-off, and field-effect tube is connected
Speed is unlikely to power off quickly, after relay conducting in parallel, electric current from relay it is upper after field-effect tube just without electric current
It flows through, such field-effect tube is not just lost, and relay is connected almost without loss.
3, after city power recovery is normal, control module 100 switches over static-switch module 200, i.e. control third is brilliant
Brake tube VT3, the 4th thyristor VT4, the 7th thyristor VT7, the 8th thyristor VT8 are first connected, then the first single-pole double throw relay
Device SW5 and the second single-pole double-throw relay SW6 connects its normally-closed contact and throws at cutter-contact point (end 0-1), guarantees that handoff procedure is continuous
Electricity to be powered by alternating current, and closes the first thyristor VT1, the second thyristor VT2, the first field-effect tube MOS1, second
Field-effect tube MOS2, and disconnect the first relay SW1, the second relay SW2, third relay SW3 and the 4th relay
SW4。
Because inverter module 300 only worked in the short transition phase, the time is short almost without fever, it is possible to reduce and hand over directly
Flow the material cost of no-break power unit.Because direct current supply module 400 almost without be lost this circuit structure feature with
And static-switch module 200 is also almost without loss, therefore this alternating current-direct current output uninterruptible power supply causes almost without because of loss
Fever, so computer room heat dissipation cost can reduce.Because direct current supply module 400 is almost without loss, the energy of saving can
It can be powered with the smaller battery of capacity with extending battery-powered time or not extending under conditions of battery-powered time, capacity
Small battery is at also originally low.
The above is only the preferred embodiment of the present invention, and therefore it does not limit the scope of the patent of the utility model,
It is all under the inventive concept of the utility model, equivalent structure made based on the specification and figures of the utility model becomes
It changes, or directly/be used in other related technical areas indirectly and be included in the scope of patent protection of the utility model.
