Description

THYTRON Battery Charger uses Thyristor switching technology for achieving the desired DC output. It basically consists of a isolation transformer, a semi conductor SCR bridge, a filter circuit with choke and capacitor to smooth out the DC output, and a control circuit. The AC mains voltage is transformed to a suitable level and fed to the SCR bridge which rectifies the AC input and feeds controlled DC output to the battery and load, after being smoothened by the filter circuit. 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.
