<p>It is described an AC-to-AC-converter for converting a first frequency AC-voltage to a second frequency AC-voltage, the converter comprising: a first converter section (101, 201) having at least a first input terminal (109) and a second input terminal (111) and having a first DC-output node (117) and a second DC-output node (119); a second converter section (103, 203) having a first DC-input nodes connected to the first DC-output node and having a second DC-input nodes connected to the second DC-output node and having at least two second output terminals (131, 133, 135); a DC-link overvoltage clamp (105, 205) coupled between the first DC-output node and the second DC-output node; and a capacitor system (107, 207), wherein the first converter section, the second converter section, the DC-link overvoltage clamp, and the capacitor system are integrated into one assembly.</p> |
