Abstract

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 maximum power recommended by the lamp manufacturer. Also, since it is desirable to implement a low-cost power factor correction, a buck PFC is proposed. The ignition process is optimized because no additional elements are necessary to ignite the lamp providing low ignition current through the switches. The design has been realized for 70, 150 and 250 W HPS lamps. Computer simulation and experimental results have validated the design method proposed.

HPS灯用PFC低成本电子镇流器的先进设计

本文介绍了一种低成本PFC电子镇流器的改进设计。逆变级采用LCC并联串联逆变器，采用谐振电流模式控制。这种控制方法避免了逆变器处理任何无功能量，最大限度地减少了开关和传导损失。此外，该设计在不超过灯制造商推荐的最大功率的情况下执行自然功率控制。此外，由于希望实现低成本的功率因数校正，因此提出了降压PFC。点火过程是优化的，因为不需要额外的元件来点燃灯，通过开关提供低点火电流。该设计已在70、150和250瓦HPS灯上实现。计算机仿真和实验结果验证了所提出的设计方法。
