Thyristor based battery charger uses Thyristor switching principle for achieving the desired DC output. It
basically consists of a transformer, a semi-conductor bridge rectifier, a filter circuit and a control circuit.
The AC mains voltage is transformed to a suitable level and fed to the rectifier bridge. After being smoothened
by the filter circuit, it rectifies the AC input and feeds controlled DC output to the battery and load.
The power output requirement is adjusted by using phase control technique which is provided by the control circuit.
The feedback signals from the output to the control circuit are used for maintaining voltage regulation and current limit.
A new innovative model uses 16-bit DSP controller (optional) for switching and control of Thyristor for achieving desired
DC output. The charger output voltage, output current, battery current, and battery temperature compensation are
controlled by the Digital Signal Processor. The charger output parameters can be set or adjusted through keypad-display
provided on the front panel with password protection. It has communication ports for local / remote monitoring of measurements
and events.

A battery charger, or recharger,is a device used to put energy into a secondary cell or rechargeable battery by forcing an
electric current through it.
The charging protocol (how much voltage or current for how long, and what to do when charging is complete, for instance)
depends on the size and type of the battery being charged. Some battery types have high tolerance for overcharging (i.e.,
continued charging after the battery has been fully charged) and can be recharged by connection to a constant voltage source
or a constant current source, depending on battery type. Simple chargers of this type must be manually disconnected at the end
of the charge cycle, and some battery types absolutely require, or may use a timer, to cut off charging current at some fixed time,
approximately when charging is complete. Other battery types cannot withstand over-charging, being damaged (reduced capacity,
reduced lifetime), over heating or even exploding. The charger may have temperature or voltage sensing circuits and a microprocessor
controller to safely adjust the charging current and voltage, determine the state of charge, and cut off at the end of charge.
