A method and an apparatus are used for power supply input connection. The apparatus according to one embodiment comprises a first switch module ( 143 _ 1 ) connected to a first power supply input (Vin 1 ); a first controller module ( 145 _ 1 ) connected to the first power supply input (Vin 1 ) and to a secondary power connection (Vc), wherein the first controller module ( 145 _ 1 ) puts the first switch module ( 143 _ 1 ) in a first operating state when a parameter relating to the first power supply input (Vin 1 ) is larger than a parameter relating to the secondary power connection (Vc), and puts the first switch module ( 143 _ 1 ) in a second operating state when the parameter relating to the first power supply input (Vin 1 ) is smaller than the parameter relating to the secondary power connection (Vc); and a first driver module ( 160 _ 1 ) connected to the first controller module ( 145 _ 1 ) and to the first switch module ( 143 _ 1 ), wherein the first driver module ( 160 _ 1 ) modifies a parameter relating to a drive characteristic of the first switch module ( 143 _ 1 ).
