This paper presents the critical design aspects addressed during the development of a 100 kW, 12.5 kV, 22 kHz, and 30 kV insulated medium frequency transformer used in a power converter. The transformers are used in a resonant multilevel converter topology producing HV DC voltage from a three phase 400 V AC industrial grid. The power converter is used to supply radio frequency systems in particle...
In order to lower the overall amplitude error of the combination of a medium voltage Rogowski coil current transducer (RCCT) with its associated readout electronics, a specific electronic architecture is presented here. It implements online accuracy monitoring, i.e. an online self calibration, that enhances accuracy performances of the electronics. This new architecture also provides transducer connection...
