Abstract:
Control circuitry for controlling the duty cycle of a magnetizing switch of a power converter containing a demagnetizing switch is described. The magnetizing switch and the demagnetizing switch are switched on within a sequence of commutation cycles in a mutually exclusive manner. The control circuitry is configured, within a commutation cycle from the sequence of commutation cycles, to determine a sensed current signal indicative of a current through the magnetizing switch. The control circuitry determines a ramp signal by adding a slope compensation signal to the sensed current signal. The control circuitry determines a threshold signal and determines a duty cycle for the magnetizing switch for the commutation cycle by comparing the ramp signal with the threshold signal. The threshold signal and/or the slope compensation signal depend on the duty cycle for the magnetizing switch of a preceding commutation cycle from the sequence of commutation cycles.

Claim (Index 5):
Control circuitry according to  claim 1 , wherein the control circuitry is configured to adapt the threshold signal and/or the slope compensation signal, such that if the adapted threshold signal and/or the slope compensation signal had been used during the preceding commutation cycle, the maximum current through the magnetizing switch during the preceding commutation cycle would have been equal to or within a predetermined range from the target peak current.
