【摘要】 本文提出一种基于微处理器控制的HID电子镇流器。电子镇流器采用有源功率因数的校正。微处理器MCU作为全桥变换器,同时具有“看门狗”功能、工作温度监控功能和系统保护等功能。本文对该系统进行了分析与设计,试验表明本系统,设计功能强、系统运行可靠,功率因数为0·98。更多还原

【Abstract】 In this paper, one new kind of HID Ballast is proposed with micro-controller used control IC, Our design differs from traditional method in that we consider many new functions. For instance, There are “watch dog”、detecting temperature and protecting ballast function in this system. In this paper, we designed the circuit framework of HID ballast and given main circuit output waveform. Experimental results have indicated that HID ballast run reliable and have strong functions that must be required in this system.;更多还原
