Section 5. Powering Lasers and Illumination Devices

Ultracompact LCD backlight inverters (15)

It has become desirable to fashion laptop computers with large area screens, leaving little room for the display’s backlight inverter electronics. Miniaturization limitations of high voltage magnetic transformers impose limits on achievable space reduction. Another voltage step-up technology, piezoelectric transformers, permits the desired size reduction and provides additional benefits. This publication describes practical piezoceramic transformers and support circuitry. Ancillary benefits of the piezoelectric approach are also described. Appended sections detail transformer operation and feedback loop considerations.
