Abstract :
The article describes a high voltage power supply utilizing a ceramic transformer with the capability of supplying about 1 mA at an output voltage of 4 kV. The power supply delivers a large output current, spanning a high voltage at output, with the efficiency of more than 80%. The ceramic transformer is newly developed for the power supply. The power supply includes feedback to stabilize the output voltage ranging from 2000 V to 4000 V with a load of more than 4 MOmega at the efficiency of about 80%. The ceramic transformer is constructed from a ceramic bar and does not include any magnetic material. The transformer is free of leakage of magnetic flux. So the high voltage power supply can be operated under a strong magnetic field
