### Abstract

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. The loss increase requires larger makeup power supply and AC supply systems. It also increases the operation costs. The system cost function has a minimum when the choke inductance is about 1.5 to 2 times larger than the magnet one. It is concluded that the application of the result will lead to a more economical and efficient resonant power supply.
