Hello friends, for my final year project im going to design a mobile charger which is powered by a renewable source (say 12v DC Wind generator) with 6v battery for backup power.
im using 2 linear voltage regulators such as LM7806 for charging the 6v backp bt from the wind generator and LM 7805 for charging the mobile phone which requires 5v..
When the charger is connected im facing the heating issues with the mobile even it shows "charging"
Please help me to design a better circuit !!
