Abstract:
1. A switch mode power converter having at least one inductive component including an output inductor and at least one synchronous rectification element, each said at least one synchronous rectification element configured to operate as a switch element, said power converter comprising a control device, wherein the control device is arranged, at initiation of startup of the power converter, to determine a duty-cycle of a startup control signal, including a normal pulse width of plural control pulses and a reduced pulse width of a first control pulse, and to provide the startup control signal to the at least one switch element, wherein during initiation of startup of the switch mode power converter the first control pulse has the reduced pulse width while all subsequent pulses are the plural control pulses of the startup control signal having same normal pulse width, such that current in the at least one inductive component of the converter is balanced.
