Abstract Regarding the current problem in the pumping station caused by DC operation power system from storage battery,"the double commutating redundancy DC power supply system" is proposed.It contains two sets of high frequency switch commutator with two independent ways of alternating current input.Each input supplies to one set of high frequency switch commutator and both of the output connect directly to the same direct current central wire through diode.The mother line is a single line without breaking and disconnecting to storage battery.Normally the two independent AC powers could supply power at the same time. All the high frequency switch commutating modules run together simultaneously to load the(electricity) of whole pumping station.Once one of the AC power system is out of use from accident,going down or termly maintaining,the other set could work independently to load the electricity of whole pumping station.The actual operation result proves that this design has the advantage of AC power supply continual switching without breaking,strong discharge capability during accident,and high expanding(capacity) etc.It could also be upgraded to multi AC power supplying electricity simultaneously to achieve the continual switching without breaking among multi power,thus could improve the reliability of the DC power.pumping station;DC power supply;double-commutating;pedundancy
