Abstract
An AC-to-AC-converter for converting a first frequency AC-voltage to a second frequency AC-voltage is disclosed. The converter includes: a first converter section which includes a first input terminal, a second input terminal, a first DC-output node, and a second DC-output node; a second converter section which includes a first DC-input node connected to the first DC-output node, a second DC-input node connected to the second DC-output node, and at least two second output terminals; a DC-link overvoltage clamp which is coupled between the first DC-output node and the second DC-output node; and a capacitor system. The first converter section, the second converter section, the DC-link overvoltage clamp, and the capacitor system are integrated into one assembly.
