Wdrożenie rozwiązania Active Front End w przetwornicach częstotliwości dużych mocy do 1,2MVA poprzez równoległe łączenie standardowych modułów falownikowych

Danfoss Drives A/S has developed a 1,2MVA Active Front End (AFE). The purpose was to realize a high power AFE as a study object. The AFE was integrated into a new dynamometer and engaged in testing of high power motor inverters. Because of limited time frames the design had to assure immediate successful operation. That was the reason that standard inverter modules have been used. The article presents the crucial problems we had to cope with when developing the AFE project. Based on the gained experience a few 1,2MVA converters with AFE solution were built and commissioned at the container gantry cranes in a harbour in Africa.
