Development and Investigation of Two Optimized Soft Switching Pulsed Power Resonant Converters for RF Applications

Abstract

This paper focuses on the closed-loop voltage control of two classical soft switching pulsed power resonant converters for radio frequency applications. Based on the optimization algorithms proposed in the previous work, the two converters are designed to produce a series of long pulse voltage waveforms, each one rated at 9MW, 120kV, 1ms, 1% voltage ripple. A novel PI + Repetitive Control strategy is employed for voltage pulse regulation, resulting in a fast rise time, reduced overshoot and constant amplitude. The soft-switching of semiconductor devices is ensured throughout the pulse by a combined frequency and phase shift modulation, in order to maximize the system conversion efficiency.
