SCR is abbreviation for Silicon Controlled Rectifier. SCR has three pins anode, cathode and gate as shown in the below figure. It is made up of there PN junction diodes also; it is solid state equivalent of gas filled triode and has around four semi conductor layers. SCR can conduct the current in a single direction or we can say SCR s are unidirectional. The SCR can be triggered only at the gate through the current. SCR will combine the features of rectifier and transistor. They are mainly used in switching applications. They can also be trig ....etc

Battery charger circuit using SCR.


Description.

A simple battery charger based on SCR is shown here.Here the SCR rectifies the AC mains voltage to
charge the battery.When the battery connected to the charger gets discharged the battery voltage
gets dropped.This inhibits the forward biasing voltage from reaching the base of the transistor Q1
through R4 and D2.This switches off the transistor.When the transistor is turned OFF,the gate of
SCR (H1) gets the triggering voltage via R1 & D3.This makes the SCR ....etc

ppt presentation of wireless battery charger using microwaves rf to dc conversion

Battery life of mobile phone is always been a problem for manufacturers. People are complaining about their mobile s battery life, that they don t have long battery life and they have to charge their phone several times. Portable electronic devices are very popular nowadays. As the usage of these portable electronic devices is increasing, the demands for longer battery life are also increasing. These batteries need to be recharged or replaced periodically. It i ....etc

The battery is charged with small amount of AC voltage or DC voltage. So if you want to charge your battery with AC source then should follow these steps, 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. Once charging is completed the circuit should automatically turned off.
