    Cap-drop offline power supply for light-load applications made SIMPLE

    Low-power applications such as e-meters often require a simple offline power supply, where 3.3V powers up a microcontroller and charges a lithium-ion battery to 4.2V. You can do this with a mains frequency power transformer or with a complex AC/DC offline power supply. Both approaches have well-known disadvantages related to weight, size and/or complexity...

    Simple tips for designing sensor circuits with extended scan interface for low power smart meter applications

    Smart meters in a smart grid have the ability to measure, control and communicate in one single device. For those battery powered smart devices like flow meters, electrical energy is precious to keeping them “smart”. Having a smarter design to lower power consumption can keep them alive for a longer time. The extended scan interface ...

    Make metering more efficient

    Low power consumption is imperative for modern meter design. Whether you’re measuring gas, water, electricity or heat, you must limit the current draw to achieve long battery life and/or prevent inaccurate readings. Fortunately, TI provides a variety of solutions to meet these requirements. In this post, I’ll review some common configurations...

    Untangling electric vehicle chargers – Getting started

    As the quite hum of electric vehicles (EV) continues to rise on our streets, public interest in making them part of our daily life is also going up. As a plug-in hybrid owner, I routinely get asked questions about ownership. The most often one being “How long does it take to charge?” and any EV owner can tell you, there isn’t really...

    Enabling long life in dual-coin cell powered meters

    Many smart meters are powered by two coin-cell batteries connected in series; after all, two batteries give twice as much battery life as a single battery. The second battery provides the energy required to meet the greater-than-10-year runtime between battery replacements that the industry requires. Unfortunately, two batteries also give twice the...

    Solar Inverter Gateways Connect Renewables to the Grid

    Solar is one of the more popular forms of renewable energy, and continues to grow in both commercial and home use. Its popularity is driven in part by solar panels becoming increasingly cheaper, which has made systems affordable not only for commercial solar farms, but also for homeowners who want to lower their carbon footprint or even sell generated...
