Patent ID: 7495425

Claim:
A buck converter comprising: an input with a first connection ( 101 ) and second connection ( 102 ), an output with a first connection ( 103 ) and second connection ( 104 ), a switch ( 110 ), a diode (D 1 ) having a cathode and an anode an inductance (L 1 ), a capacitor (C 1 ), wherein the first connection ( 101 ) of the input is connected to the first connection ( 103 ) of the output via a series circuit comprised of the switch ( 110 ) and the inductance (L 1 ), the cathode of the diode (D 1 ) is connected to the connection between the switch ( 110 ) and the inductance (L 1 ), the anode of the diode (D 1 ) is connected to the second connection ( 102 ) of the input and to the second connection ( 104 ) of the output, and the capacitor (C 1 ) is connected in parallel with the connections ( 103 , 104 ) of the output, such that the switch ( 110 ) is triggered from a first state to a second state by combining a first signal with a second signal, wherein the switch is triggered by combining the first signal with the second signal and a third signal, wherein the second signal is an essentially triangular shaped signal generated by a saw tooth generator, and means for adding the current signal and the essentially triangular shaped signal by integration of a voltage in the inductance (L 1 ) and an additional voltage.
