    Abstract: The DC/DC converter with an output current which is periodically variable over time comprises a control network (11) which generates a variable reference signal (Refl) for the input current which is substantially smoothed and obtained from the difference between the output voltage (V out ) and a reference voltage (V ref ). The substantially smoothed reference signal (Refl) causes a variation in the duty cycle of the converter in order to compensate for the variation in the output voltage (V out ) resulting from a variation in the output current (I out ).

    Abstract: The circuit comprises a plurality of supply modules for delivering current to a common load. Each supply module (3) is equipped with a driving circuit (23, 25, 27) for controlling the current delivered by the module. The supply modules are connected together by a share bus (9) on which a signal is present for balancing the current delivered by each supply module, in such a way as to control and reduce the difference between the current delivered by a dominant supply module and the current delivered by the remaining supply modules of the circuit. Associated to each supply module are means (31) for generating a PWM signal, the duration of which is proportional to the current delivered by the respective supply module. In addition, each supply module is connected to the share bus in such a way that on the latter there is present a digital share signal, which is a function of the digital PWM signal generated by the dominant supply module. In each supply module, means are provided for generating an error signal, the said means generating, on the basis of the PWM signal of the module itself and on the basis of the digital share signal, an error signal, which constitutes a feedback signal for the driving circuit of the supply module.
