Optimization of resonant power supply circuit

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 approximate design method were developed. The effect of choke inductance on the component´s rating and cost was determined. It was found that the increase of choke inductance reduces the maximum and increases the minimum choke current, leading to a significant increase in system losses. The maximum voltage is independent of the choke inductance. The described change of choke current reduces the current of the bypass thyristor switch and the capacitor bank switch, which results in cost reduction. The increase of choke inductance reduces the size of capacitor banks
