Abstract
A burst mode inverter that drives a discharge tube lamp in a manner that produces more emissions. A DC power supplier produces DC power. An inverter converts that DC power to AC power having a Pulse Width Modulated frequency that is between 2 and 3 times the system's frame frequency. A duty cycle controller controls the duty-on-time of the Pulse Width Modulation frequency so as to be with the range of about 40% to 100%.
