英飞凌汽车HID前灯镇流器及PFC控制解决方案主要由5个MOSFET、2个高电压驱动器、1个PFC控制器和1个HID灯镇流器控制器构成，具体电路如下图所示。

英飞凌汽车HID前灯镇流器及PFC控制方案电路示意图。

MOSFET可选择英飞凌的N沟道MOSFET（500V或600V的CoolMOS C3/CoolMOS CP），

PFC控制器可选择英飞凌的DCM PFC-IC（TDA4863-2）或CCM PFC-IC（ICE1PCS01/02）。

有源功率因子控制器TDA4863-2是英飞凌针对开关电源（SMPS）最新推出的PFC-DCM（非连续传导模式）控制IC，前两代产品分别是TDA4862和TDA4863。它们主要优化用于为电子镇流器和离线SMPS提供非常紧凑和高性价比的PFC解决方案，完全与世界标准相兼容。通过使用一个针对非连续工作模式的零电流检测器，它们允许实现一个接近1的功率因子和杰出的THD。

TDA4862、TDA4863和TDA4863-2的主要特性包括：1）功率因子接近1；2）像有源谐波滤波器一样控制升压转换器，以得到更低的THD；3）低电流启动；4）针对非连续工作模式的零电流检测器；5）输出过压保护；6）输出欠压锁定；7）内部启动定时器；8）带主动关断功能的图腾极输出；9）内部边沿消隐LEB；10）正弦电流消耗。

与TD4862相比，TDA4863和TDA4863-2的改进为：1）非常低启动电流；2）非常低比较器和乘法器失调；3）针对由MOSFET开关引起的低失真干扰的高复杂度放大器；4）更精确的过压阈值；5）更高的栅极驱动能力（仅适用TD4863-2）。

有源功率因子控制器ICE1PCS01/02是英飞凌针对有源CCM（连续传导模式）功率因子校正转换器而推出的8脚控制IC，The unique average current control allows for low THD at all load ranges and excellent compensation of line voltage varations. The soft-start and the open-loop-protection provide high reliability and optimum operating conditions for SIC(silicon carbide) diodes. ICE2PCS01/02 are the 2nd generation of Continuous Conduction Mode (CCM) PFC controllers, which employ BiCMOS technology.

Compared to the first generation of ICE1PCS01/02, the new ICs have lower internal reference trimmed at 3V. They also have other advantages such as wider Vcc operating range, improved internal oscillator and additional direct bulk capacitor over-voltage protection.

Major Features include:

1. Ease of use with few external components

2. Average current control

3. External current and voltage loop compensation for greater user fexibility

4. Programmable switching (50-250kHz) for ICE1PCS01/ICE2PCS01

5. Trimmed internal fixed switching frequency for ICE1PCS02/ICE2PCS02(65kHz+5% at 25oC)

6. Direct sensing, input brown-out detection with hysteresis for ICE1PCS02/ICE2PCS02

7. Max. duty cycle of 95% (typ)

8. Trimmed internal reference voltage (5V+2%) for ICE1PCS01/02

9. Vcc under-voltage lock-out

10. Cycle by cycle peak current limit.

11. Output over-voltage protection

12. Open loop detection

13. Output under-voltage detection

14. Enhanced dynamic response

15. Soft overcurrent protection

16. Fulfills class D spec. of IEC1000-3-2
