Abstract
High-voltage power supplies (HVPS) are critical components in industrial microwave generators, directly influencing efficiency, stability, and operational reliability. Conventional single-phase HVPS systems for single-magnetron microwave generators often suffer from voltage fluctuations, harmonic distortions, and reduced energy efficiency, which can compromise both magnetron lifespan and the consistency of industrial processes. This research presents the development and validation of a novel three-phase high-voltage power architecture specifically designed for single-magnetron microwave generators, integrating advanced transformer modeling, leakage flux optimization, and simulation-based performance verification.
The proposed architecture employs a three-phase transformer network with delta-wye configuration, coupled with a full-wave rectification stage and optimized smoothing and damping circuits. Transformer design incorporates non-linear B-H curve modeling and analytical flux computation to minimize core saturation and leakage effects. MATLAB Simulink simulations were conducted to model dynamic load behavior, voltage regulation, harmonic response, and transient characteristics, allowing detailed evaluation of system performance under nominal and step-load conditions. Optimization procedures were applied to refine transformer turns ratios, damping networks, and control parameters, ensuring maximum efficiency and operational stability (Bassoui et al., 2014).
Analytical validation was performed by calculating the leakage flux, induced currents, and transformer losses, and comparing these results with simulation outputs. The findings indicate that the three-phase HVPS achieves voltage deviations below 2% under varying load conditions, reduces total harmonic distortion to 4.5%, and provides efficiency exceeding 92%, demonstrating superior performance over conventional single-phase systems. Thermal analysis further confirms that optimized leakage flux reduces transformer heating, supporting continuous industrial operation without derating.
The study contributes a rigorous framework for the design, modeling, and validation of three-phase HVPS systems for single-magnetron microwave generators, providing a practical methodology that can be scaled for multi-magnetron or higher-power applications. This research bridges a critical gap in industrial microwave power supply design by combining theoretical modeling, simulation validation, and practical optimization, offering a validated, high-performance solution for precision-driven industrial processes. The implications extend to energy-efficient microwave material
processing, chemical manufacturing, and semiconductor applications, where precise, stable, and reliable power delivery is essential.
