Abstract :
For fast-cycling synchrotrons, resonant-type ring magnet power supplies are commonly used to provide a DC-biased AC excitation for the ring magnets. Up to the present, this power supply system has been analyzed using simplified analytical approximation, namely assuming the resonant frequency of the ring magnet network is fixed and equal to the accelerator frequency. This paper presents a frequency-domain analysis technique for a more accurate analysis of resonant-type ring magnet power supplies. This approach identifies that, with the variation of the resonant frequency, the operating conditions of the power supply change quite dramatically because of the high and value of the resonant network. The analytical results are verified, using both experimental results and simulation results
