A high Q R-L-C series resonant circuit has been analyzed with the consideration of using high T, superconductor (HTS) technology. With HTS techniques, a very high Q circuit can be achieved; consequently special aspects such as high voltage generation can be practically realized. Theoretical study has been carried out, as well as a prototype device has been made for the experimental verification. This paper will describe this high voltage generation method with theoretical analysis of the prototype device. Key Words: High temperature superconductor; Inductor; Resonant circuit; Quality factor. and the maximum build-up voltage is related with the R-C-L resonant circuit Q value by For using a DC power supply with an electronic switch to reverse the polarity, the maximum voltage VCmax can be expressed as F(t) = (4VBht)[sinmt + (l/3)sin3mt + (l/5)sin5mt +...J (3) The generator only resonates on the first harmonic with amplitude of 4VBht.
