This paper describes the performance of a high-voltage power supply incorporating a ceramic transformer. Since the transformer is constructed using a ceramic bar containing no magnetic material, the power supply can operate under a magnetic field of 1.5 Tesla with no degradation of performance. Feedback is used to stabilize high-voltage output such that a supply voltage of 3 V provides from 1500 to 2500 V at a load of more than 10 MΩ with efficiency higher than 50%; and with a supply voltage of 2 V, 3000 V is supplied at a load of 20 MΩ. In fact, a supply voltage of 5 V is sufficient to provide 4000 V at the same load. A network of high-voltage power supplies is also described. Most functions of the power supply are thereby monitored and controlled through the network
