Abstract: The present invention relates to AC-DC conversion in power electronics. In particular, the present invention is directed at a thyristor rectifier, which may be employed in an electric motor drive. The rectifier includes three thyristors and three diodes, wherein the thyristors are connected to a positive rectifier output and the three diodes are connected to a negative rectifier output. The present invention also relates to an electric motor drive comprising a corresponding thyristor rectifier. In general, the present invention may be used in a frequency converter for an electric motor drive, but it can also be used in non-drive application.
