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。

Abstract: To simulate and design the digital electrodeless lamp ballast, a model of electrodeless lamp was used, which based on "transformersmagnetizing inductanceleakage inductance" lamp equivalent distributed circuit model and considered leakage effects. And the ballast used boundary conduction control strategy to achieve power factor correction. Then, a prototype digital lamp ballast was built with integrated control chip. The measured results of the ballast was consistent with the simulation results. In this case, it is a good engineering practice guidance.
