Repetitive Control for High-Performance Resonant Pulsed Power Supply in Radio Frequency Applications

Abstract

This paper presents a novel three-phase series resonant parallel loaded resonant converter topology for radio frequency applications. The proposed converter is capable of producing a series of “long pulses” as output voltage, each one lasting 1 ms in time. Three individual single-phase resonant stages are able to independently operate in conjunction with three separate single-phase output rectification stages. Due to this important feature, the converter has a strong ability of rejecting the influence of unbalance in the resonant tanks. A proportional-integral + repetitive control strategy has been used for the output pulsed voltage regulation, resulting in a fast rise time, a reduced overshoot, and a constant amplitude. The soft switching of semiconductor devices is ensured at full power by a combined frequency and phase shift modulation, even in the presence of large tank unbalances.
