Control of High Voltage Series Resonant Power Supply for Industrial Magnetrons

This paper considers the design of a high voltage high frequency compact power supply for applications where the load is variable and/or nonlinear. One particular application where this is the case is when driving an industrial magnetron with a variable output radio frequency (RF) energy requirement. A compact power supply based on a series resonant series loaded (SRSL) converter with an extended combined phase and frequency control is proposed.
