Float Cum Boost Charger

The system can be operated either in float mode or in boost mode. The float mode is meant for supplying the DC continuous load and at the same time, trickle charging the battery to keep it in fully charged condition.The Boost mode is basically meant for quick charging the battery after a heavy discharge, so as to restore the capacity of the battery within minimum time. At this time load will be fed thru’ dropper diode.The charger may also be operated either in auto or in manual mode. In the manual mode the output voltagecurrent may be varied within the limits by external potentiometer(s). In auto mode the output voltage is held constant at a preset value.
