METHOD FOR SUPPLYING AND DISCHARGING POWER TO AND FROM A RESISTIVE-INDUCTIVE LOAD, AND RECTIFIER USED THEREIN

摘要

The aim of the invention is to supply power to excitation windings in order to generate magnetic fields, preferably for activating superconducting coils. Said aim is achieved by using an AC transformer and triggering the coil via a rectifier having little power loss. Preferably, a two-way rectifier using a freewheeling circuit is utilized in the associated device, thus preventing losses when power is supplied and especially also when power is discharged.
