摘要
采用考虑漏感影响的"变压器-励磁电感-漏感"无极灯等效电路模型仿真数字式无极灯镇流器的实现原理,采用临界导通控制策略实现功率因数校正。在仿真基础上,采用集成控制芯片设计数字式无极灯的样机。实测结果与仿真结果一致,对工程实践有良好的指导作用。
To simulate and design the digital electrodeless lamp ballast, a model of electrodeless lamp was used, which based on ＂transformers-magnetizing inductance-leakage inductance＂ lamp equivalent distributed circuit model and considered leakage effects. And the ballast used boundary conduction control strategy to a- chieve power factor correction. Then, a prototype digital lamp ballast was built with integrated control The measured results of the ballast was consistent with the simulation results. In this case, it is a good chip. engi-neering practice guidance.
