Patent ID: 6967429

Claim:
A power output stage for capacitive loads comprising: an energy storage inductance ( 8 ), one end of which is connected to a reference potential ( 9 ) and which at the opposite end is connected on the input side to a power supply connection ( 1 ) and on the output side to a secondary energy storage capacitance ( 4 ); a primary energy storage capacitance ( 3 ) which is connected upstream of the energy storage inductance ( 8 ) on the input side, with the primary energy storage capacitance ( 3 ) once again being connected on the input side via a primary switching element ( 12 ) with the reference potential ( 9 ), and a secondary switching element ( 14 ) which is connected in series with the secondary energy storage capacitance ( 4 ), characterized in that the input of the power output stage is clocked by an additional switch ( 20 ).
