Adjusting feedback gain in a fluorescent lamp dimming control |
摘要 |
By monitoring line current before the lamps of a fluorescent lighting system start, an estimate of full load current is made. The estimate is used to adjust the current feedback gain to avoid any current level overflow in the control. The normalized values used within the control result in consistent relative light levels independent of load size.
