14 V 4 A BATTERY CHARGER/ POWER SUPPLY ELECTRONIC PROJECT DIAGRAM BASIC AND TUTORIALS

This is a basic electronic project of Battery Charger/ Power supply.


Operational amplifier A1 directly drives the VN64GA with the error signal to control the output voltage. Peak rectifier D1, C1 supplies error amplifier A1 and the reference zener. This extra drive voltage must exceed its source voltage by several volts for the VN64GA to pass full load current.

The output voltage is pulsating dc, which is quite satisfactory for battery charging,
