Multi phases - dc / dc converter and multi phases - the same voltage converter system

摘要

Comprising a plurality of converter means (11a, 11b.., 11f), the power wall position, the input parts and initial parts are connected in parallel; an output current detector means (5), which detects an output current io; and a control device (15), which the number of devices in operation n of the plurality of converter means (11a, 11b.., 11f) as a function of the detected output current io is determined, and a shift control of the determined number n of devices in operation in the case of a switching frequency f is carried out in such a way that their phases differ from one another. The product of the number of devices in operation, n and the switching frequency f drops out of the region of a round radio out of the tape. This provides for a multi phases - dc / dc converter and a multi phases - the same voltage converter system, the noise generated by switching the device do not influence the broadcast band.
