【摘要】 传统的电感式镇流器存在体积大、效率低等缺点。为逐步替代传统的电感式镇流器,介绍了一种基于DSP控制的5 kW紫外灯电子镇流器,采用了精简的三级式电子镇流器拓扑,同时依据紫外灯的伏安特性设计了分阶段PI控制的策略。然后以DSP为核心制作并调试了控制系统硬件。最后依此研制了5 kW紫外灯电子镇流器的样机,测试结果证明了该电子镇流器满足实际生产需要。更多还原

【Abstract】 The traditional inductive ballast has many disadvantages,such as large volume,low efficiency.A kind of electronic ballast based on DSP is introduced,and the electronic ballast will gradually replace traditional inductive ballast.This electronic ballast uses tidy three-stage topology,and a strategy of segmented PI control is designed based on ultraviolet lamp’s ampere-voltage character.Then,the hardware of control system is designed and tested based on DSP.Finally,an electronic ballast sample for 5 kW ultraviolet lamp is developed,and the test results are well.更多还原
