Left panel, superconducting rectifier circuit used to convert AC currents into DC using four superconducting diodes (blue) connected by superconducting interconnects and one smoothing capacitor (C ...

The circuit was compared to a popular KBU8B silicon diode rectifier. At an input voltage of 5 V rms at 50 Hz and a constant load of 5 A dc, the KBU8B’s output was 4.45 V dc, average, measured ...
