Single Solar Cell Trickle Charges 3- To 16-V Battery In-Circuit
Many battery-powered applications use very little power when idle and have short-duration operating periods. Thus, the total energy used is very small. It would be convenient to incorporate solar cells in these devices to charge the batteries. However, the number of cells needed to charge a given battery voltage is close to Vb/0.6, thereby necessitating an array of solar cells, series connected. The circuit in the figure addresses that issue by employing a...
