ELECTRONIC BALLAST WITH POWER THERMAL CUTBACK |
摘要 |
<p>An electronic ballast with power thermal cutback including an electronic ballast operably connected to provide power to a lamp, the electronic ballast having a PFC converter (HO) operable to receive a PFC input voltage (112) and operable to provide a DC bus voltage on a DC bus (114); a DC/AC converter (120) operable to receive the DC bus voltage from the DC bus (114) and to provide AC power (122) to the lamp (140) at an AC output frequency; a compensator (130) responsive to an electronic ballast condition parameter, the compensator (130) being operable to provide a compensator signal to at least one of the PFC converter (110) and the DC/AC converter (120). At least one of the PFC converter (110) and the DC/AC converter (120) is responsive to the compensator signal to reduce the power to the lamp (140) when the electronic ballast condition parameter passes a threshold.</p> |
