Therefore, power converters which do not require heavy inductors are of great interest. In this contrbution power converters with non-resonant output filters are investigated fpr reducing weight and volume ofe the magnetic components. The design of such a power converter for a travelling wave type ultrasonic type motor is presented. Implementation highlights like the design of the filters and the concept of an universal digital modulator are outlined and measured results are presented. Finally the concept is compared to resonant converters under consideration of weight, volume and efficiency.","lang":"eng"}],"_id":"4064","user_id":"74004","file_date_updated":"2020-11-24T11:34:15Z","title":"PWM-Converter for Travelling Wave Type Ultrasonic Motors.","publication":"ACTUATOR 2002","department":[{"_id":"DEP6020"}],"file":[{"file_name":"02actuator_kauczor_schulte_froehleke_442.pdf","creator":"czr-e2t","file_id":"4065","content_type":"application/pdf","relation":"main_file","file_size":480447,"date_updated":"2020-11-24T11:34:15Z","access_level":"local","date_created":"2020-11-24T11:34:15Z"}],"page":"442 - 445","ddc":["620"],"language":[{"iso":"eng"}],"author":[{"first_name":"Thomas","last_name":"Schulte","full_name":"Schulte, Thomas","id":"46242"},{"first_name":"Norbert","full_name":"Fröhleke, Norbert","last_name":"Fröhleke"}],"publication_status":"published","has_accepted_license":"1","citation":{"havard":"T.
