Abstract
Precise and accurate measurements of the DC critical current of high-Tc superconductors often require a current supply that has high input-to-output isolation, high isolation from ground and low output ripple. Also, to ensure precise current control, the supply should have low current drift and its input-output characteristic should be linear. A design for a simple and inexpensive current supply that has these characteristics is presented. The primary power sources is a 12 V wet-cell battery and the typical operating range is from 10mA to 10 A. The supply's current ripple isCitation
