This thesis aims at the research and development of the power system for driving an innovative transmission-target X-Ray Tube. This power system can be applied to the 40-Watt transmission-target X-Ray Tube developed by NanoRay Biotech Co. In the thesis, this power system of the transmission-target X-ray Tube is launched and tested in an environment compliant with “The Ionizing Radiation Protection Regulations” to validate its functionality and feasibility of the power system.
The power system in this thesis is divided into three levels, High-Voltage Level: (0 ~ –80 kVDC), Filament Heating Level: (0 ~ 1.75 ADC), and Bias Voltage Level: (0 ~ 300 VDC). Each level has a wide range of output variations to meet the power requirements for the overall X-ray tube.
Furthermore, in this thesis, the supplied-voltage of all levels is powered by 24 VDC to facilitate the cases if this product needs modifications to use the battery power in the future. About the topology, with the use of full-bridge inverters, transformers, and rectifier circuits, it allows each level to adopt the same topological design. This approach has simplified the variation and the quantity of the analog controller ICs in the front stage.
Secondary, in the system control, it utilizes a digital controller combined with a wired communication module and a human-machine interface. This allows the users to send commands to the digital controller through the human-machine interface of a computer. Based on the voltage setting entered by the user, the corresponding required for the duty cycle is decided. Comparing the feedback duty cycles with the calculated ones, the analog controller IC modulates the duty cycle to stabilize the output voltage as well as to achieve reaching the set value of the output voltage.
In addition, through the use of a voltage sampling circuit, the sampled voltage feedback is sent to the digital controller and thus returned to the computer for achieving a real-time display of the operating voltages of each level on the human-machine interface.
Finally, this thesis derives the mathematical model of the system, and establishes comprehensive design considerations. Through computer simulations with respect to the actual results, and verified by an ionization chamber for dose measurement with actual X-ray firings, the feasibility of proposed system is validated.
