Battery Charging Circuit Diagram Using Scr. Scr battery chargers use scrs silicon controlled rectifiers along with conventional. Battery charger using scr.
Battery charger block diagram. Humming noise while charging. So if you want to charge your battery with ac source we need first limit the large ac voltage need to filter the ac voltage to remove the noise regulate and get the constant voltage and then give the resulting voltage to the battery for charging.
The shaded portion will be our main area of discussion.
The ac main voltage is given to the step down transformer the voltage should be down to 20v approx. Circuit diagram of the battery charger circuit using scr can be seen below. When the battery. It plugs directly into standard 120v 15a 60 hz ac outlets receptacles for use in off board shelf or on board built in applications.
