摘要: The measured performance of compact fluorescent lamps (CFLs) and some rectified incandescent lamps, which can cause considerable harmonic distortion the input power, is discussed. These include both electronically magnetically ballasted CFLs with poor power factors and/or high harmonics. Using model a building's electrical load, it shown that there little for concern supply quality problems when are less than 25% total load. Several reasonable low-cost passive circuits improve factor as well suppress described. use active will be more effective but costly best considered above 30 W special applications where minimum harmonics required. >
