The resonance power supply is widely used and proved to be an efficient method to supply accelerator magnets. The literature describes several power supply circuits, but no comprehensive theory of operation is presented. The authors present a mathema

A resonant power supply has been proposed to power rapid cycling accelerator magnets. In the present work, the resonant power supply circuit is optimized by selecting the most feasible choke inductance. For this optimization, a computer model and an

The authors analyze different energy-replacement methods for the resonant power supply and present a new method. This method uses a 24-pulse converter to regulate the magnet current during flat-top and injection periods and replaces the energy loss b

The particles in a rapid cycling accelerator are accelerated by RF cavities, which are tuned by DC-biased ferrite cores. The tuning is achieved by the regulation of bias current, which is produced by a power supply. The tuning magnet power supply uti

A design study for an accelerator-driven spallation-neutron source is underway at Los Alamos. The driver, based on the LAMPF facility, produces a 1-MW proton beam and is upgradable to 5 MW. After linear acceleration to full energy, an H/sup -/ beam i

A new circuit concept for the exciter to produce a 100-kA current pulse with a 1-ms flat top is presented. In every half-cycle a capacitor generates a current pulse. A thyristor-controlled rectifier charges the capacitor to the supply voltage, and a
