Abstract
A 350 kV/20 mA high voltage DC power supply for X-ray tube is designed to use as a control circuit with Digital Signal Processor (DSP). The power use the 380 V/50 Hz three-phase electric as input signal, and output high voltage via rectifier filter, full bridge inverter, transformer booster and voltage doubling rectifier. The inverter circuit implements voltage adjustment by generating SPWM of different duty ratios in DSP. The Maxwell software is employed to calculate the distribution of the electric field as designing the transformer, and the maximum field strength is 78.521 kV/mm in winding. It is available to design the layer insulation of transformer windowing with the polyimide film in accordance with the electric field. Voltage doubling rectifier circuit uses C - W positive and negative two-way voltage doubling rectifier circuit which is a wide application in X-ray Optical Source. The numerical simulation indicates that the overall design of power is legitimate and the parameters can reach the expected requirements.
