| 摘要 |
In a circuit arrangement for the operation of high-pressure gas discharge lamps by means of a pulsatory supply current having a pulse recurrence frequency between 50 and 2000 Hz and a duty cycle between 0.2 and 0.8, a current having a high-frequency between 20 and 200 kHz is superimposed on the current pulses and with a modulation ratio beween 0.3 and 1. The high-frequency is an integral multiple of the pulse recurrence frequency. Thus, flickering of the lamps is avoided. |
