Claim:
1. A method of regulating energy in a power converter, comprising: receiving with a voltage regulation circuit a first signal representative of an output voltage of the power converter; receiving with a current regulation circuit a second signal representative of a current of the power converter; determining an output current of the power converter in response to at least one of the first signal received by the voltage regulation circuit and the second signal received by the current regulation circuit, wherein a first transition point corresponds to a first output transition voltage of the output voltage of the power converter and a first output transition current of the output current of the power converter, wherein the first transition point is between an inner transition point and an outer transition point, wherein the inner transition point corresponds to an inner transition point voltage of the output voltage of the power converter and an inner transition point current of the output current of the power converter, wherein the outer transition point corresponds to an outer transition point voltage of the output voltage of the power converter and an outer transition point current of the output current of the power converter, wherein a second transition point corresponds to a second output transition voltage of the output voltage of the power converter and a second output transition current of the output current of the power converter, wherein the second transition point is between an upper transition point and a lower transition point, wherein the upper transition point corresponds to an upper transition point voltage of the output voltage of the power converter and an upper transition point current of the output current of the power converter, wherein the lower transition point corresponds to a lower transition point voltage of the output voltage of the power converter and a lower transition point current of the output current of the power converter, and wherein a third transition point corresponds to a third output transition voltage of the output voltage of the power converter and a third output transition current of the output current of the power converter; switching a power switch of the power converter to regulate the output voltage and the output current of the power converter between the first transition point and the second transition point; switching the power switch of the power converter to regulate the output current of the power converter between the second transition point and the third transition point; and switching the power switch of the power converter to regulate the output current of the power converter between the third transition point and a short circuit current at zero output voltage.
