A novel digital control theory is proposed for the metal halide lamp electronic ballast used for the projector. The resonant ignition with LCSCP mode is adopted here, an adaptive digital control method for ignition is proposed to overcome the problem of the deviation for the passive components. A simple power closed loop method is proposed to make the lamp power constant without the power over ...
In this paper, an advanced design of a low-cost electronic ballast with PFC for HPS lamps is presented. The inverter stage is based on LCC parallel-series inverter with resonant current mode control. This control method avoids the inverter handling any reactive energy, minimizing both switching and conduction losses. Also, the design performs a natural power control without exceeding the maximu...
