Auxiliary power supply for high voltage applications

摘要

An auxiliary power supply system comprises an electric power source (4) at ground potential (G), a power supply circuit (5) at high voltage potential (19), and at least a first and a second insulating transmission link. The first (2) and the second (3) insulating transmission links are based on differing energy transmission principles, with the first transmission link (2) making use of a contact-less transmission principle, and the second transmission link (4) being based on transmission of mechanical energy.
