Abstract

DC60 (03/09/56) The invention power supplies include the power supply unit (1), the power booster unit (reactor (21), switch (22)) which increases the The voltage is supplied from the power source (1) by a switching control, a smoothing circuit (3), which smoothes the output voltage from the reinforcement unit, a stacker ( 23) which is arranged between the booster unit and the smoothing circuit (3) to prevent reverse flow. It is directed through the reinforcing unit and the chopping unit (4), which are connected to the stacker (23) in parallel to intercept the casters that pass through the stacker (23). ) To it itself.The power supply equipment according to this invention will include the power supply unit (1) auxiliary unit. Power (reactor set (21), switch (22), which increases the applied voltage to the power supply (1) by regulating the rectifying circuit rectification (3), which adjusts the voltage outside the Stabilizer unit smoothing shaft (23), which is arranged during smoothing circuit reinforcement unit (3) to prevent reverse flow. Of the gantry through the auxiliary unit and the chopping unit (4) which were connected to the sorter (23) in Parallel traits to chop the cyst flowing through the sorter (23) towards it.

Claims (5)

Disclaimer (all) which will not appear on the advertisement page: 1. Power converters which include Unit of power supply The booster unit increases the voltage discharged from the power supply unit by controlling the switching unit smoothing, which smoothes the resistance voltage from the reinforcement unit.
