CONTROLLED POWER DISSIPATION IN A LINK PATH IN A LIGHTING SYSTEM |
摘要 |
In at least one embodiment, a lighting system includes a link path power dissipation circuit to actively and selectively control power dissipation of excess energy in a switching power converter of the lighting system. The link path power dissipation circuit dissipates power through a link path of the switching power converter by controlling a link current of the switching power converter. In at least one embodiment, the controller controls the link path power dissipation circuit to limit the link current with a current source and dissipate power in the current source. In at least one embodiment, the link path power dissipation circuit includes a switch to limit the link current and dissipate power in the link path. |
