Abstract

Describes particular requirements for electronic invertors and converters for high-frequency operation of tubular cold-cathode discharge lamps used in signs and luminous discharge tube installations and operating with an output voltage exceeding 1000 V but not exceeding 10000 V for direct connection to supply voltages not exceeding 1000 V at 50 Hz or 60 Hz or 1000 V d.c.
