Abstract
This paper presented the design and performance analysis of a dynamo-type HTS flux pump for a 10 kW superconducting generator. The HTS field coil of a 10 kW superconducting generator was designed and fabricated. The induced DC current, output voltage, and dynamic resistance of the flux pump connected to the HTS field coil were estimated using electric circuit equations. They were tested at various rotational speeds and air gaps, and the test results were compared with the estimated results. The performance was confirmed by applying a flux pump to the 10 kW superconducting generator. As a result, as the rotational speed of the flux pump increased, the induced DC current of the flux pump connected to the HTS field coil increased proportionally. As the air gap of the flux pump increased, the induced DC current decreased. A sufficient current was induced in the field coil to produce a 10 kW output.
