Description
3Phase Float cum Boost Battery Charger :
The 3Ph. input is fed to the stepdown transformer with Single Phasing Protection
( 415Vac/150Vac ). This 150Vac is then rectified and fed to voltage regulator and
filter circuits. This output voltage of 150Vdc is provided at output terminals to
charge the Batteries. Whenever the battery gets discharged the intelligent IC
checks the drop in battery voltage and provide a pulse to Thyristor through Gate to
conduct and provide the output to battery at the same time when battery is fully
charged the gate voltage is made zero because drain-source current is also almost
zero hence the Thyristor stops conducting and stops providing output to charge the
battery. So when the Battery is fully charged no overcharging is there to damage
the Battery. At this stage Output voltage remains same but Charging current is
zero. It is called as Float mode.
