| Abstract: | Due to the complex start-up process and timing control requirements,control circuit built with conventional analog control is unavoidably cumbersome.A set of universal fluorescent electronic ballast based on MC56F8013 DSP was designed.The APFC is achieved by Boost topology circuit.By changing the switch frequency,preheating of the light before its illuminating,high voltage resonance point igniting and dimming ability was realized.The new ballast has lots of merits,such as simple structure,flexible control and easier to realize advanced arithmetic,strong commonality,automatic fault detection and diagnosis. |
