How a SCR helps in charging of a battery?

The SCR gets triggered with a voltage at its Gate terminal through the resistor R1 and diode D1. It then starts rectifying the AC voltage, though only for the half cycle. As the DC current starts flowing to the battery through the resistor R2, the battery gets charged.

What type of circuit is used in charging system?

There are two types of regulators, namely type or conventional type and type of IC. The point type/conventional uses two coils to adjust the altenator’s output voltage. While the IC Regulator uses an IC circuit (Integrated Circuit) to regulate the output voltage.

How many SCR are used in battery charger?

Two SCRs are used in this design, one is a high power SCR that charges the battery by supplying the required current, while the other low power SCR monitors the voltage level of the battery, and cuts-off the gate supply to the power SCR as soon as the battery voltage reaches the full charge level.

What is battery circuit?

Essentials. A battery is a device that stores chemical energy and converts it to electrical energy. The chemical reactions in a battery involve the flow of electrons from one material (electrode) to another, through an external circuit. The flow of electrons provides an electric current that can be used to do work.

What are the different types of battery chargers?

There are two different types of battery chargers on the market today – Timer Controlled chargers and Smart chargers (also called Intelligent chargers), each for a different budget, (Timer Controlled are less expensive), but more importantly, using two different technologies.

How does a battery charger work in a substation?

Most high voltage substations house either a sealed or flooded cell battery bank. In a normal functioning system, the batteries provide very little current. A continuous load current maintains a constant charge on the battery. The battery charger provides a current if the charge exceeds the output capability.

What is SCR circuit?

A silicon controlled rectifier or semiconductor controlled rectifier is a four-layer solid-state current-controlling device. SCRs are unidirectional devices (i.e. can conduct current only in one direction) as opposed to TRIACs, which are bidirectional (i.e. charge carriers can flow through them in either direction).
