Abstract
This paper describes a new developed telecom rectifier. The device is fed by the usual mains voltage, has state of the art technology as well as high requirements especially for the efficiency. Also the suppression of interferences to the environment is of importance. This includes EMI and low harmonics on the line input current. All these conditions need a very careful design. A new method is used in order to get the best possible efficiency at nominal line voltage.
