CONTINUOUS VERY HIGH VOLTAGE SUPPLY CIRCUIT BY SEMICONDUCTOR CONVERTER FOR TELEVISION TUBES IN PARTICULAR

摘要

A power supply circuit for converting an input d.c. voltage into a first and a second d.c. output voltage. The power supply circuit includes the series arrangement of an inductor and a controllable switch for receiving the input voltage, the first output voltage being obtained from the resulting square-wave voltage across the inductor. A series resonant circuit followed by a peak-peak rectifier is coupled to the inductor for providing the second output voltage. Arranged as such, variations in a load connected to receive one of the output voltages has substantially no effect on the other output voltage.
