The article describes a photomultiplier high voltage power supply incorporating a piezoelectric ceramic transformer. The ceramic transformer utilizes piezoelectric effect to generate high voltage and can be operated under a strong magnetic field. The high voltage power supply is intended to produce high voltage efficiently under a strong magnetic field. The high voltage power supply includes feedback to stabilize the output high voltage. Stability of the feedback is investigated from the viewpoint of beats. The circuit of a high voltage power supply is shown together with its performance. The high voltage power supply is capable of supplying a high voltage ranging from 1500 V to 2500 V against a load of less than 10 MΩ. The efficiency of the high voltage power supply is better than 50 percent
