Modeling of a Single-Phase High-Voltage Power Supply for a Single Magnetron

Industrial microwave generators operating at 2.45 GHz commonly use magnetrons as microwave sources, requiring robust and reliable high-voltage (HV) power supplies. This paper presents a nonlinear electrical model of a single-phase HV power supply feeding a single magnetron, based on a magnetic-shunt transformer and a voltage-doubler rectifier. The model accounts for the nonlinear magnetic behavior of the transformer and the electrical characteristics of the magnetron. The developed model provides a useful tool for the analysis and optimization of single-phase magnetron power supplies used in industrial microwave applications.
