The described DC to AC inverter efficiently controls the amount of electrical power used to drive a cold cathode fluorescent lamp (CCFL). Additionally, during striking of the CCFL, a higher energy initial energy pulse is used. During normal operation, a lower energy pulse is used.

Method for starting a discharge lamp using high energy initial pulse

The described DC to AC inverter efficiently controls the amount of electrical power used to drive a cold cathode fluorescent lamp (CCFL). The inverter uses a full bridge that is controlled to deliver energy to the CCFL using pulse width modulation (PWM). Additionally, during striking of the CCFL, a wider initial energy pulse is used. During normal operation, a lower energy pulse is used.
