Abstract
The present High Intensity Discharge electronic lamp ballast uses a 'set of controls' that can be performed by controlling energy delivery by the 'line side converter' to the “lamp side inverter”. This set of controls comprises: 1) open circuit voltage control, 2) breakdown voltage amplitude control, 3) glow-to-arc transition current control, 4) “initial arc development” current control, 5) “arc stabilization” current control, 6) lamp power control, 7) lamp dimming, 8) “lamp rectification” current control, and 9) short circuit and lamp fault protections. One of the primary advantages of this “line side converter” energy delivery control method is that it doesn't need to vary the lamp operating frequency to achieve the above-noted controls.
