A high voltage power supply operating under a magnetic field

The article describes a network of high voltage power supplies where the high voltage power supply incorporates a ceramic transformer utilizing piezoelectric effect to generate high voltage. The ceramic transformer is constructed from a ceramic bar and does not include any magnetic material. So it is expected that the high voltage power supply can operate under a magnetic field. The high voltage power supply was tested under a magnetic field of 1.5 tesla. The performance of the power supply was almost intact in the magnetic field. The power supply includes feedback to stabilize the high voltage output, supplying from 1500 V to 2500 V with a load of more than 10MΩ at a efficiency higher than 50%. From a supply voltage of 2 V, the power supply can provide about 3000 V at a load of 20 MΩ. A supply voltage of 5 V is large enough to provide 4000 V at the same load. The high voltage power supply is equipped with an interface chip with a network. Most functions of the high voltage power supply are kept under the control of the chip, and are then monitored and controlled through the network
