Electronic Ballasts and Other Lighting Applications

 

Compact fluorescent lamps, high-intensity discharge (HID) lighting, high-brightness LEDs, dimming and control systems for all types of lighting -- these are some examples of the applications of power electronics to lighting. For more conventional fluorescent tubes, electronic ballast offer better performance, lower energy consumption, and less wear and tear than more traditional magnetic ballasts.

 

Lighting technology is changing rapidly, and power electronics is the primary enabler of this change. Modern electronic ballasts operate at frequencies of a few tens of kilohertz to eliminate flicker and acoustic noise associated with discharge lighting. Small sizes and fast operation allow advanced lamps to be used in applications from cameras to cars.
