Single Phase SCR Full Bridge Converter, Model: SPBC – 101

The phase controlled converter can operate either in rectification mode or in inversion mode. In rectification mode, AC power is converted to DC power and in inversion mode DC power is converted to AC power. The unit is capable to operate in both modes.

The Phase Controlled rectifiers using SCR’s are used to obtained controlled DC output voltage from the fixed AC mains input voltage. The output voltage is varied by controlling the firing angle of the SCR’s.

AC – DC converters are used extensively in industrial applications, specially in variable DC speed drives.

The Phase Controlled converters can be classified in Single Phase and Three Phase converters.The Phase Controlled converters can be classified in Single Phase and Three Phase converters.
