用于非隔离单开关DC-DC变换器开关故障诊断和电容ESR监测的高效罗氏线圈传感器应用

Power switches and electrolytic capacitors are the most vulnerable components in the power electronic converters. Any failure in these components may result in severe damages, if no remedial action is employed. Prior to any remedy, the first step is fault diagnosis. In this paper, a new type of Rogowski coil sensor is proposed. The sensor captures the inductor current derivative, which contains su...
