Abstract

Power is supplied to excitation windings in order to generate magnetic fields, preferably for activating superconducting coils. An AC transformer is used, and triggering of the coil is performed via a rectifier having little power loss. Preferably, a two-way rectifier using a freewheeling circuit is utilized in the associate device, thus preventing losses when power is supplied and especially when the power is discharged.
