KRETS FOER TAENDNING OCH BEGRAENSNING AV STROEMMEN I EN GASURLADDNINGSLAMPA |
摘要 |
<p>A variable frequency ac source drives a gas discharge lamp connected as a damping element in an otherwise high Q L-C circuit. Commutation of the ac source voltage is initiated as the instantaneous current drawn from the source equals a predetermined reference current level. Prior to lamp ignition the ac source drives the L-C circuit at resonance causing a voltage buildup which initiates an ignition. After ignition the source limits lamp current to provide a ballasting function.</p> |
