Ultra-low-power-Energy-Harvester-and-Battery-Charger

The electronic gadgets are the most popular devices that are being used by everyone today, and how it is quickly drained up is the most common problem. The circuit as shown in the reference design is the STEVAL-ISV09V1, which is an evaluation board for SPV1050. The SPV1050 is a transformerless thermoelectric generators and PV modules energy harvester, comes with high efficiency for any harvesting source and has a maximum of 70mA maximum battery charging current. It also allows to charge any type of battery which includes thin film batteries which need proper monitoring provision of the length of charging and voltage level of batteries to ensure that battery life is preserve. The SPV1050 has a programmable maximum power point tracker (MPPT), which can be done by changing the value of external resistors. Read more
