Energy Harvesting with Low Power Solar Panels

Trevor Barcelo - Product Line Manager - Battery Management Feb 4th 2013
As global energy demand continues to drive oil prices higher design engineers across all application spaces investigate techniques to take advantage of “free” energy. Photovoltaic solar cells provide the most common alternative energy. Countless articles and studies have been done on Maximum Power Point Tracking ...

Maximum Power Point Control Simplifies Energy Harvesting

Fran Hoffart - Applications Engineer Nov 8th 2010
There is an increasing market for low power electronic devices located in remote locations, away from the power grid. Ideally, the power for these devices should be generated on-site using renewable energy. Perhaps the most visible form of renewable energy is from the sun. Converting this solar energy into electrical energy ...

LTC4070 50mA/500mA Li-Ion/Polymer Shunt Battery Charger System - Video Product Brief

Steve Knoth - Senior Product Marketing Engineer Jul 9th 2010
The LTC4070 allows simple charging of Li-Ion/Polymer batteries from very low current, intermittent or continuous charging sources. The 450nA to 50mA operating current makes charging possible from previously unusable sources. With the addition of an external pass device, shunt current may be boosted to 500mA. Stacked cell high ...

LTC4070 Photovoltaic Charger with Extremely Low Leakage When Not Charging

Jan 29th 2010
A photovoltaic (PV) application for the LTC4070 is illustrated in this example. In this application, transistor Q1 has been added to further reduce the already low quiescent current of the LTC4070 to achieve extremely low battery discharge when the PV cells are not charging the battery. In long battery life applications, Q1 ...

LTC3109/LTC4070 Unipolar Energy Harvester Charges Battery Backup

Jan 29th 2010
The LTC3109 is a highly integrated DC/DC converter ideal for harvesting surplus energy from extremely low input voltage sources such as TEGs (thermoelectric generators) and thermopiles. Its unique, proprietary autopolarity topology allows it to operate from input voltages as low as 30mV, regardless of polarity. In this circuit, ...
