摘要： The invention relates to an AC/DC converter circuit (100) and a method for converting N≧2 AC supply voltages (U1, U2, U3) into DC voltage. This is achieved by feeding the AC supply voltages to first terminals (a1, a2, a3) of full bridge converters (11, 12, 13), wherein the second terminals (b1, b2, b3) of these rectifiers are coupled to each other. The outputs (d11, d1′, d2, d2′, d3, d3′) of the rectifiers are fed to the DC terminals of intermediate converters (21, 22, 23). The AC terminals (e1, e1′, e2, e2′, e3, e3′) of the intermediate converters are connected to the primary sides of transformers (31, 32, 33), wherein the secondary sides of these transformers are provided to further rectifiers (41, 42, 43). The circuit design allows using MosFETs of limited voltage capability for processing 380 V three-phase AC current, thus achieving a high efficiency.
