This article proposes the combination of filament-heating and cavity-driven circuit with gain-frequency regulation control for magnetrons. This article is motivated because some existent magnetron-driven systems often adopted two resonant circuits individually for filament heating and cavity driving, resulting in limited flexibility of power delivery and modulation. Therefore, this article develops an integrated resonant power circuit that excels at the capability improvement of filament heating and cavity driving in the same time such that the design process and power conversion can be simplified while the output power is effectively induced. Meanwhile, by considering that the microwave source emission in the magnetron is often affected by the variation of internal impedance, this article includes a gain-frequency tracking control. Through this way of controller design, both heating power and cavity power are found to be well regulated and the constant-power operation can be better achieved. To confirm the effectiveness of this magnetron-driven design, both circuit simulation and hardware realization are accomplished. Analysis results and experimental outcome support the practicality of the approach, benefiting the realization of microwave energy applications.
