Single Phase Silicon Controlled Bridge Converter

In ac circuits the phase controlled rectifiercan be turned on at any angle a with respectto the applied voltage polarity. The angle a isoftenly called the firing angle. These circuitsare characterized as controlled rectifiers orconverters. In present model study of suchcontrolled rectifier in bridge configuration isperformed. The prime aim of firing circuit toproduce trigger pulses to the thyristors atdifferent firing angles.
