MIXED MODE CONTROL FOR BALLAST CIRCUIT |
摘要 |
A ballast system in which mixed-mode gate signals are used to control the ballast circuit so as to produce a more straight ballast lines such than only a single solution exists between ballast lines and lamp lines over the whole operating range, whereby a stable of lamp performance is achieved. In a preferred embodiment, symmetric and asymmetric modes are arranged alternatively in every other switching cycle to produce mixed-mode PWM gate signals.
