Abstract
A DC/DC converter () having a plurality n of two-pole inverters () connected in parallel or in series, n transformers (T, T) and n two-pole rectifiers () connected in parallel or in series is described. One inverter () each and one rectifier () each are connected to a transformer (T, T). The inverters (') are in turn connected to a control which is provided for frequency-synchronous actuation of the inverters (′) with a 180°/n phase shift. According to the invention, leakage inductances (L, L) of the transformers (T, T, T′, T′), together with capacitors (C, C) of the inverters (′) and/or capacitors (C, C) of the rectifiers (′), form in each case a resonating circuit whose resonant frequency is substantially twice as great as a clock frequency of the control signal. Furthermore, an AC/DC converter () is described which has a DC/DC converter () according to the invention with an AC/DC stage () connected on the input side.
