Patent ID: 7626369

Claim:
A load line regulated switched mode power converter for supplying an output voltage and an output current to a load, the switched mode power converter comprising: an inductor, a switch coupled to the inductor, a first impedance, a second impedance, and a power converter controller including: a first sense circuit for obtaining momentary information on a first current flowing through the first impedance, the first current being related to the output current, means for determining a difference between a zero load voltage and the output voltage to obtain a difference signal, a second sense circuit for obtaining further information on a second current flowing through the second impedance, the second current being related to the first current, an integrator for integrating a difference between the further information and the difference signal to obtain a correction signal, and a switch controller for receiving the difference signal, the momentary information and the correction signal to control the switch for obtaining a substantially zero correction signal in a steady state, the switch controller including: a driver for receiving a first driver signal and a second driver signal to operate the switch when a level of the first driver signal reaches a level of the second driver signal, and means for receiving the correction signal for correcting either: (i) the momentary information to obtain corrected momentary information, wherein the first driver signal is the corrected momentary information and the second driver signal is the difference signal, or (ii) the difference signal to obtain a corrected difference signal, wherein the first driver signal is the momentary information and the second driver signal is the corrected difference signal, or (iii) the momentary information to obtain corrected momentary information and the difference signal to obtain a corrected difference signal, wherein the first driver signal is the corrected momentary information and the second driver signal is the corrected difference signal.
