DEVICE FOR SUPPLYING AUXILIARY POWER TO AN ITEM OF EQUIPMENT ON A CURRENT-LIMITED POWER SUPPLY BUS

摘要

The power supply circuit for powering equipment via a current-limited power supply bus at a nominal voltage (Vb) of the equipment includes an auxiliary power supply circuit comprising an energy storage member and a trigger member for triggering auxiliary power supply to the equipment from the storage member via a voltage-reducing converter for reducing the auxiliary voltage to the nominal voltage.
