中文摘要:
      我国计划在未来五年全国范围内,安装2.4亿块智能电能表,最终安装智能电能表的总量应该是5亿块。智能电能表是长期连续工作其低功耗运行对节能减排,提高供电企业经济效益具有重要意义。因此采用宽电压,低功耗电源管理IC及合理的设计, 提高电能表可靠性和性价比,以满足智能电能表国家标准。每户电能表非通讯状态的功耗降低到0.4~0.6W以下,并且降低智能电能表电源部分元器件成本20%~30%,规模效益十分巨大。
英文摘要:
      Smart Electricity Meter (SE-meter) is quickly gaining popularity in China in recent years. The 5-year plan calls for in the installation of 240 million SE-meters. This will bring the total of SE-meter installation to 500 million units. SE-meter is required to work non-stop for at least 7 years, consequently the power consumption becomes a very important issue. The lower power consumption will directly translate into long-term savings for the urban electricity suppliers, ultimately the savings for us consumers. This article presents a low power supply design for SE-meter applications. The design meets and exceeds the power and EMI requirements, per Chinese government regulations. The power consumptions during stand-by mode is reduced to 0.4~0.6W per meter, while reducing the overall power supply component cost by 20~30% at the same time. This article details this low power supply design for SE-meters.
