This paper describes a software developed for the simulation of high voltage (up to 125 kV), high frequency power supply for radiology equipment. The main components of the power supply are an AC-DC conversion stage, a high frequency inverter feeding a resonant load. The resonant load is the impedance reflected to the inverter side of the, high voltage high frequency transformer Seeding the X-ray tube. The software has modules for each of the components of the converter mentioned above, which can be modified to accommodate configuration changes. The set of time domain equations for each modules are capable of representing the operation of the related circuits at different stares of the switches. Predictor-Modifier-Corrector method is used for solving the resulting set of equations. A control module is incorporated into the software, In the presentation here the control module has a fuzzy controller. The paper first illustrates solution accuracy of the model used. Then the prediction accuracy of the performance of the system is demonstrated.
